Gas mileage and cost of fill up.
« on: April 27, 2018, 12:24:16 PM »
Just a quick question wondering what kind of gas mileage and what type of rig you have?
As well how many miles/km you would get on the fill up.
Was looking at a small class c for the wife and I to see the country in and was just wondering what kind of expense one could expect.

Thanks

Assuming you're talking about a gas powered rig you'll be in the 8-10 MPG range. Gas tanks range from around 25 to around 40 gallons on small Cs I believe. So if you fill a 3/4 empty 40 gallon tank at today's prices you're in the $90 range, which will take you about 300 miles.

Your signature line shows a RAM 1500 5.7L and a 26 foot (nominal) trailer.   I'm guessing you will be lucky to see 10 mpg and maybe as low as 7-8 if any headwinds, hilly terrain, etc., but I haven't seen any towing mpg figures on a late model 5.7L to validate that. Hopefully somebody here has one like yours and can comment.

when I had a 31 foot class C I was lucky to see 7.  But the poor thing was near full capacity before we put a piece of straw in it.  We towed an accord with it most of the time.  Just make sure you have enough cargo carrying capacity to pack appropriately and still be safe. 

It will bite you somewhere if you overload it.  Maybe not right away but you will have a mechanical running around overloaded.

2002 Safari Trek 28 ft class A 17,000 GVWR with 8.1L Chevy Vortec gas engine with no toad I average just under 9 mpg on long highway trips cruising at around 65-68 mph, I would do better driving slower, but most of my trips are through Texas (and other western states) where even 2 lane highways have a 75 mph speed limit.

I just bought a class B Mercedes Roadtrek adventurous.  It has a Diesel engine and a 30 gallon fuel tank, I think.  Anyway, last week I drove it from Florida to Connecticut (1600 miles) and I averaged approximately 17-19 miles per gallon. Depending on where you are, diesel can cost from 2.75 - 3.50 per gallon. Overall, I was quite pleased with the performance especially when I compared it to my SUV gas mileage which is about 20 miles to the gallon. Hope this helps. Enjoy your road tripping!

I kept gas records for 8 years on my 28 foot Class C. The tank was 55 gallons.
My generator draws out of the same tank so that throws off your MPG.

My annual average was always hovering around 8 mpg with 55 gallon tank and I was fully loaded.
First off I never let my gas get below a half tank except in emergencies (running from hurricane!)

I wanted that half tank cushion for emergency generator use. When I had a breakdown in 99F weather on side of hot steamy interstate, I so needed that generator to stay alive and cool until help arrived which took several hours in spite of me being on the outskirts of a major city. I was towed to a closed repair facility. The humidity was out of sight, there was no electric hookup since they parked me outside of the locked gates. I ran the generator another 12 hours just to stay cool until they opened up to make repairs to my rig.

So you're probably going to be looking at buying half tanks of gas at a time, if you want the security of being comfortable if things go wrong. I always topped up my gas before setting up camp, that way if anything went wrong, flood or hurricane... I had a full tank of gas to hit the road.

Most of the time I traveled with a full tank of water too. I was fulltiming 24/7. While I did not tow a car, I had a bicycle and a cargo carrier hanging off my hitch.

I ran my generator 1-2 hours, at least once a month to keep it happy. Other times, especially in summer, I used it more because I traveled with a dog. When I was stopping to shop, I had to run the generator to keep him alive. Mostly I could drive with just the dash air running. This will work fine in a Class C but not a Class A.

However, there were times when I traveled on hot steamy days when I did run the generator and AC because I wanted the rig pre-cooled when I arrived at camp.

My driving style is rather sedate, I was slow to accelerate and often coasted to my stops. I didn't really push it hard and often chose by ways and scenic routes where I could putter around at 45-55mph rather than breakneck speed of 80 on interstates. Even on the interstate, I preferred 55-65.

Sure there were times when my average MPG would zip up to 10mpg, mostly in the winter cooler months and flat lands of Florida, but then the summer and extra generator use would bring it back down again.

When planning my trips, I always figured gas costs at 6pmg and added another 50% to the cost for detours and whimsical sightseeing. This way I had leftover gas money after every trip.  8)

I hope this helps!

Our coach has a 150 gallon tank, and over the past four years, we've averaged 7.2 mpg while towing our Jeep. That usually sounds pretty bad to people who are new to RVing, but when you consider that the RV weighs in at about 40,000 lbs and has everything we need to be comfortable - just as when we're at home - that's not bad at all. It's even more impressive when you consider that our Jeep gets to where we're going without using a drop of fuel.

Well Gary you are right I tow my trailer and I avg 8 mph and I thought it was on the thirsty side and was curious to know if a motorhome was better on gas, apparently not especially considering one would almost need to tow a vehicle.
If I was to ever switch I would consider a very small class c or a class b or a smaller TT.

Off topic since the topic is a class C.  We are not towing but get 7mpg with a 45 ft. class A diesel at 70 to 75 mph on the interstate.  This was about 2500 miles from Texas through Colorado into Washington.  For us being able to travel in an apartment on wheels and get 7 mpg is great.  Next trip will be 2500 miles with toad, part in Calif with a 55mph limit when towing, so we'll see how the mpg goes.  But anywhere near 7 mpg will be great.  150 gallon tank which we keep at least half full for the generator since the fuel pickup tube does not go below 1/4 tank.  So a couple hundred bucks for 1/2 tank of diesel.

But I will say, slow down and save.  If MPG is your concern, slow down.

Well Gary you are right I tow my trailer and I avg 8 mph and I thought it was on the thirsty side and was curious to know if a motorhome was better on gas, apparently not especially considering one would almost need to tow a vehicle.

Right, a motorhome is still a big box that has to be pulled around by a big gas engine (or pushed around by a big diesel engine). Not too different from your pickup towing the trailer. You can expect similar mileage... 8mpg is pretty standard, and might even be considered on the high end! The good thing about RVing is that (usually) the long drives are not too frequent, so the fuel costs are manageable as a part of your overall travel budget.

It's not uncommon for me to have a 400 mile day out here in the Western part of the country to get to my first night's stop.

I just have to ask Why? Why do you want to go on the trip of a lifetime in a very small class c or a class b or a smaller TT??? For the same money as what you have invested you could be in comfortable coach with all the amenities of home. Something that is quieter, rides better, has bigger tanks and more storage. Look at this coach as an example.

Look around on the website there are several in this range.
Just because you buy a small "C" or "B" doesn't mean the milage will  be that good. If you get between 6 and 9 you will be in the range of most RV's. Your mileage can vary more than that just based on driving conditions.
You will need a toad to maximise your experience. My RV gets 9 mpg so you park the RV and go exploring in the toad. My toad gets 30 mpg which one do you want to drive when out exploring?

I don't know if this will help you since you seem interested in a Class C. My Class A 39' gasser gets about 7.5-8.0/mpg on flat ground by itself. Put my toad behind it and consider that not every road if flat, and my mileage goes to 6.5-7.0 on the highway and 5.5-6.0 in city traffic. I have a 75 gallon tank but can only run it down to ¼ full if I don't want to lose my generator, so I plan on getting it filled every 45-50 gallons, meaning I get an average of about 300 miles per fill up. This works out just fine for me since I usually don't travel more than 300-350 miles per day when getting to a destination and can plan on filling my tank when I stop for the night.

Previous posters are correct by telling you that using a toad rather than driving a small Class C everywhere you go is going to be more efficient. For one thing, you won't have to worry about maneuvering your RV through city traffic and parking lots when trying to do simple things like shopping for groceries. You'll also not have to worry about size restrictions when traveling through state and national parks. Using your toad is simply more convenient, not to mention the better gas mileage.

I would like to offer an answer as to “why”...for me, traveling with just my dog, and traveling only when I feel like it, I decided that the small class b (mine is 22.9’) was a good fit. It has everything I need and want, but is easy to drive, park and “live” in. I admit that it was not inexpensive by any means since I bought a Mercedes Roadtrek but my investment so far has made for easy traveling with all the benefits of RV life. That’s what works for me right now, but maybe if I am spending more time traveling than I currently do, I will go bigger. 👍😃

Dcm, my currrent setup is similiar to your and we get anywhere from 12-15mpg when towing. Your TT specs look a little bit heavier than
ours. We are usually around 6200lbs loaded and in CA I never drive over 57 there are too many "eager" CHP officers that would like to
show you the error of your ways  :) :) :)

True, but one needs to also weigh the speed and number of those 18 wheelers that are blowing by with their bow pressure waves against driving slower to get better fuel economy.

Just a quick question wondering what kind of gas mileage and what type of rig you have?
As well how many miles/km you would get on the fill up.
Was looking at a small class c for the wife and I to see the country in and was just wondering what kind of expense one could expect.

Thanks

I have a 32ft class with ford V10. I get 8mpg but use 7 mpg as a budgetary guide for gas as wind and grade will effect mileage.   I have a 50 (perhaps 55 gal tank) and always fuel up at 1/2 tank...so we do 150-200 miles between gas stops.  I plan my trips around RV friendly gas stations/truckstops, especially now with the Ford Escape towable we have which puts some limits on access into gas stations.

We have a 2004 Winnebago Sightseer 30', Workhorse chassis 8.1L (496 c.i.) In the 3+ years we've owned it, we've gotten a bit over 8 mpg ONE time...the rest of the 10,000+ miles have been around 7.5 when we weren't towing a car, or 6.5 or so when towing. ALL of our towing is in the western states, and I (almost) never drive faster than 60 mph.
