I have a problem, I have a 2005 Dodge 1500 4x4 and was told I needed a 3/4-1 ton truck to pull a 5th wheel RV. I would really like a 5th wheel.  However, my wife works for a campground and we see 1/2 ton trucks pulling 5th wheels frequently, especially the Toyota Tundra. What gives? any information on this would be greatly appreciated. I dont know if I could just purchase additions to be able to tow one with my Ram, such as air bags.
Thanks
John
 
John, it's really all about weights and loading. If your truck is rated for the load you are considering putting on it and pulling with it, then there is no problem, but if it isn't, then you could be putting the people with you as well as others on the road at risk. Just because others are doing it, doesn't make it safe. Trucks are rated for loads using multiple factors, for instance frame strength, wheel base, axle and spring ratings, tires, etc, so although air bags may take some sagging out, they won't do anything for the extra load that is being placed on the rest of the components. Since I've pulled trailers, but not fifth wheels, I'm really not sure if they make ones light enough for half ton trucks or not...I'm sure others will chime in; but I would check your truck's gross rear axle weight rating (door sticker), it's gross combined weight rating (door sticker), and it's maximum towing capacity (manual? or Trailer Life) so you will know by the numbers whether it's doable.
 
Most will recommend at LEAST a "3/4 ton" (ie F250, Chevy 2500 or the equiv) to pull a fifth wheel.  It has more to do with frame rigidity and truck weight than towing capacity.

You'll see many threads on this, but as a card carrying member of the newly appointed "Tow Police", I feel compelled to pass this on.  Most half tonners aren't up to the task SAFELY.  Can they pull it down the highway?  Of course.  Can they control the trailer in a strong crosswind, a sway condition, or down a steep grade if the trailer brakes fail?  Maybe.......  Remember...this is the safety of your family we're talking about here.  Serious stuff.  And few things are scarier than having the tail wag the dog when a semi passes you or watching the ditch get closer when a strong gust of wind hits and knowing there's nothing you can do about it.

Find out your trucks GROSS COMBINED WEIGHT RATING.  Should be in owners manual for your cab, engine, transmission, and rear end combo.  Take off 10% immediately if you tow out here in the steep stuff....big mountains, etc. Now take that number and subtract out the weight of your truck, passengers, fuel, luggage, camping stuff, and anything else you lug around.  The balance is the upper limit of what you can safely tow.  That doesn't mean you can do it comfortably, just safely.

Remember, the closer you get to your trucks limit, the less fun towing is.  As you approach the limit, towing in the hills can turn into a white knuckle freak show quickly.  In most practical terms, there is no such thing as "too much truck".  An F350 Powerstroke dually will gladly pull along a 3000 lb 18' trailer. 

I too see a lot of half tonners pulling decent sized fivers.  Many of them, IMHO, are one piece of bad luck away from disaster.  Hope this helps.
 
Generic terms like 1/2 or 3/4 ton are meaningless. You need the exact specs for you  truck.

I guessed since you did not give them. Look here and redo with your exact specs if  guessed wrong.

Your limiting factor appears to be GVWR it appears to be 6650 in all cases.  My guess is that with a loaded truck and then a 1000 lb of hitch weight you will be well over that.

There are some 5th wheels that are designed from the factory to be light weight and be pulled by 1/2 tons. If you ain't bought already you might look at some of them.

My truck is a 2006 Dodge Ram 4 door 4x4 short box. GAVW for front and rear are 3900lbs  GVWR6700lbs... 4.7 liter V8

There are many half ton towable 5th wheels out there, but not new ones. I am looking at replacing my 10K Avion in my signature with a late 80's~ early 90's Alpenlite 27' with no slide.
4000~5000 pounds empty, 6600 GVWR.
1000 pounds on the pin.
About 18" shorter in height than my 5ver.
We want to travel and a trailer like that will be a dream to tow behind my diesel truck. I can and do tow the big trailer but for long trips with many miles, we would like a lighter and shorter rig that can go into just about every National Park campground. Camping is the goal for us.

+1 to that...

Why would you want to set you and your family for a white knuckle trip possibly? Wouldn't you rather have a big roomy truck and plenty of cargo carrying capacity that is very stable and you can relax towing your trailer. I can tell you I own both a 1/2 ton (5.9L V8, auto) and 3/4 ton (5.9L Diesel Manual) Dodge Ram trucks. I can tell you my 31' Jayco pulls like a dream with the 3/4 ton where the 1/2 ton struggles to even move it. Always best to have too much truck than not enough.

I WOULDNT want to set myself and my family up for a dangerous white knuckle trip. Thats why Im inquiring about this situation.
 
The trouble is, the new "light" trailers are all pushing 7K to start with.
 
These threads always get lively discussion!  I know, I've been following them for a few months on various forums as I work to select an acceptable 5er to pull behind my 2009 Silverado 1500 (crew cab, short wb, trailering package, etc).  I've had a salesmen (and his sale manager!) try to put me in a trailer "marketed for 1/2 ton trucks" (Keystone's Cougar with helium technology), who's dry pin weight alone, would have put me at 97% of my rear GAWR!  I've found salesmen generally turn a blind eye to the vertical forces of gravity and payload capacity.  Buyer be aware!

While not the ideal, but with close attention to the math and maintenance and upkeep of the TV, I'm looking forward to the purchase of Keystone's Springdale 247FWRLLS.  Based on the weight of items we've removed when renting previous TTs, we estimate we will be at 75% of towing capacity and 92% of rear GAWR.  This is based on a recent weight of the truck with my wife, myself, full tank of fuel and the hitch installed.  Load rating of current tires is acceptable, but we will increase the load rating on the next set for an extra measure of comfort.  Oil, transmission and rear-end fluid changes will be performed more frequently with close attention paid to filings and "haze" in the fluids to indicate premature wear.

I'll report back from time to time, let folks know where we've been and how things are holding up.

Safe Travels!

I towed a Terry 5th wheel with a 2001 Chevy K1500 for several years.  The weight was within specs but just barely.  It would work, but it just wasn't any fun. :(  Very difficult to use the cruise control.  The trans would kick down on every little hill and the engine would scream.  I rarely got more than 7mpg towing. 

If you're OK on the weight and won't be on the road much, then I'd say you're OK, but if you're planning on towing quite a bit, don't do it.
 
I have a friend that is getting ready to move from their hybrid trailer to a 5Ver, they have a new F150 with the V6 Ecoboost.  While I was constantly advising him to move to an F250, I've been pretty amazed with the specs of the units he has been showing me that are well within his limits, wow, they are really making the units lighter. 
 
Some general thoughts on F-150 trucks and their equivalents across the brands. 

The most significant factor in determining the towability of a given trailer is its weight as actually loaded for travel.  In estimating that actual weight on a prospective purchase we use the trailers GVWR (unladen weight + max cargo capacity) as provided in the mfr specs or on the trailer's DOT plate.  This GVWR is compared to the tow rating of a prospective tow vehicle.  That tow rating is based on the truck carrying a full load of fuel and a 154-lb driver, only.  To allow for large drivers, passengers, truck junk, and the weight of the hitch mechanism, I like to allow a safety factor of 10% in the listed tow rating of a truck 10%.  (20% for normally aspirated gasoline engines operated in the West.)

Take the 2012 Jayco Eagle Super Lite HT 23.5RBS as an exemplar of the lightest 5th wheels, Jayco's specs on the rig list its GVWR at 9950 lbs.  Using the 10% safety factor, that trailer would require a truck with a 11,550-lb tow rating.

Using the 2012 Ford F-150 as the exemplar of '1/2 ton' trucks and the Trailer Life 2012 Guide to Towing tables, I find that only one group of F-150s comes close to that tow rating -- those sporting the turbocharged 3.5L V6 EcoBoost gasoline engine.  Those engines turn out 11,000-11,300 tow ratings with the 3.73:1 rear end.  All other engines and rear end ratios run 1000-2000 lbs lighter.

Based on that, I would say that the F-150, half-ton class of trucks is a doubtful 5th wheel puller -- bar select units with that Ecoboost engine and the 3.73 axle ratio.

Keep in mind that many trailers have an unbelievable cargo capacity as well. My friend's Wildcat extralite has a lightweight of 6950 or so, and a cargo capacity of 4141 pounds!
In this scenario, the trailer's GVWR is not what matters. Load it up as you would use it, and weigh it. If you get 4100 pounds in it you must be hauling concrete blocks out to the job site :D

I don't know what the manufacturer was doing here. Maybe it got between common axle sizes and they spec'ed it out at the bigger axle, disregarding a typical need.

Northwood Manufacturing does the same thing with their Nash and Arctic Fox lines, and in the process builds trailers with near legendary ruggedness. My 28' Arctic Fox 26x came from the factory with over 3000 lbs. of carrying capacity.

All it means is the frame and running gear is overspec'd, which isn't a bad thing.  Instead of everything running at it's maximum rating,  things like tires, springs, brakes, axles, etc. have an extra 20-30% safety factor built-in.
