That is a huge trailer to be towing back and forth to California, plus I think you have great ideas but are being unrealistic about the joy of traveling with a lot of kids and grandkids. I think that you will NOT want to take the whole set of kids and grandkids with you. Or at least you won't want to do that after the first trip!!
Much better is to get something smaller that sleeps maybe 5-6 and put the bigger kids in a tent. And you can always get the parents to come visit you, and bring the kids with them. Or, depending on their age, get a teenager to drive a couple of his siblings or cousins to visit you.
You did not mention ages, but I can guarantee that teenagers are good for only a few years. Once they hit about 15 or 16, they will have part-time jobs, or friends, but in any case will no longer want to camp with grandparents. (Trust me on this one.
I'm listening to you guys, plus I'm also understanding that some of the places we're wanting to go ("up in the mountains") would require a smaller trailer than the mega-giant 45" we would otherwise get.
Our oldest grandaughter will be ten this December. We've got a 3-yr old, and three that are literally about 6-months or younger. So we've got a few years until they reach the dreaded "apathetic teenage existentialist." And while our 10-yr old can change, I sure do believe that she'll stay as sweet as she is now! She would have a ball camping!
I mean, every family dynamic is obviously different. I see that several of you like TheBar, Tulecreeper and Babe2201 are pretty darn suspicious of of our family plan being unrealistic hopium. And then there are a couple like Mark_K5LXP and ButchW who had things work out very well in their family trips.
I can only say that yes, we've told them and actually they're all pretty excited both for us (because this is their mom's dream and they're happy when their mom gets her dreams satisfied) and because they genuine love being together as a family. Most of the time, we've done a huge Airbnb and had the whole clan meet in places like Big Bear or Lake Tahoe or somewhere where we can all meet. We do it once a year, sometimes twice. It's not easy to get everyone on the same schedule, but they try and usually at the end of the day literally everyone shows up. We always end up overflowing whatever house we rent. It's quite probable that we'll continue to do that, and we'd be able to pull up in our trailer and use it for "overflow" and we'd obviously have our own digs in our own bed. That would be fine.
And then yes, if we were in town, most of the kids would very eagerly do a weekend camping trip. Actually, a couple of the girls and their husbands have made camping out of their vehicles (one has a Nissan Rogue and they've camped out of it like 40 times!). Our oldest daughter wouldn't "camp" but she'd RV if she had a decent indoor bed.
I mean, no, they wouldn't want to go RV camp with us every week, but even we're not that crazy. But yes, I truly do believe that we'd get each one of the oldest five being very happy to do a getaway with their folks at least once a year (twice maybe) in addition to the giant mega-Airbnd-gathering that I think we'd still do just because of the logistics.
That said, my wife and I are discussing what kind of use we think we'd put a trailer through with the kids and listening to you guys about how that would practically work out. We ultimately plan to do most of our trips just us. And then there's times when we'd take my mom to visit her family that live in other states.
My wife's plans actually MOSTLY are just about the two of us travelling to places we would otherwise never see. The kids are just "gravy" as they say.oo.
In response to TonyL who advised me not to get hung up on horsepower and torque, I'm sorry, but I just can't help myself. My wife is the one who is the most excited about the RV lifestyle. Me, I mostly just want that truck! And yes, it might be a mental condition. As a veteran, I assure you I've already been diagnosed with a couple of those.
We do understand that these things DEPRECIATE. But we also understand that at the end of the day, they are still assets and there will still be residual value if and when we decide our adventure is over. Versus flying all over and using hotels most of which don't have kitchens.
Yes, a dually would be better for pure towing. If we did end up getting a much larger trailer, we'd probably have to end up with one. As it is, I'm looking right now for a 1-ton single rear wheel diesel truck. And figuring on overinflating the tires when we're towing. But that's the kind of thing we have to figure out.
DutchmenSport advises we start going and looking. My thoughts were to kind of do some research first before doing that partially to keep my wife from getting too excited about something before we'd done any thinking and zipping off to the moon.
She is VERY excited about looking for trailers. We've got a daughter's wedding this weekend to be part of (it's a five-plus-hour drive to get there and my wife's been very active assisting our daughter with plans). So we've been pretty busy. But after that, she is very eager to hit the RV dealers.
Gary RV_Wizard says, "my message is to stop thinking like a car buyer and start thinking like a home buyer" by focusing on the practicalities and essentials. I'm watching vids on what goes wrong with trailers, how bad various problems can be, how to fix things. We're not buying a trailer in place of a home, but my wife is planning on outings that will have us travelling for at least three months a year - not counting the kids. So it actually will be a home.
