Hey BDR, I'd say that it's like anything in life, everyone has different tastes and needs, and there are people on this board who's dream of perfect camping involves tents in remote locations and for other's it's a Prevost on the coast with bubbly while sitting in the hot-tub. Both sound pretty good to me!
My current truck was purchased long before we decided to camp with a trailer. I had a friend who is a Ford Service Manager steer me toward the Tundra when I was looking, and I've been happy since. The Double Cab and Crew Cabs were not available then, and the oldest has outgrown the back seat of the Access Cab. However, this truck has given me 160,000 miles of no problems. Routine maintenance, brakes done twice (mainly because I just won't tow a trailer with brakes that are old - they weren't in too bad shape when replaced). I get a consistent 18 mpg non-towing in summer, around 17 in winter (different fuel blend up here in winter). And it accelerates quick for a truck, has the 4.7 V8. However, because it has that high mileage, we are looking for the next option.
With that said, my father has driven a lot of 3/4 tons and up, a lot with diesels, some gas. My Tundra can not compete with that for towing ability (or for testosterone replacement therapy), but it makes a good daily driver. If I were rich, I'd own a one ton diesel of some sort. But, I'm an average Joe working to get to each Friday and each $ makes a difference.
We ended up finding a used 29 foot Jayco travel trailer that was in great shape and had three bunks for the kids. We looked at a lot of used trailers and the Jayco trailers seemed to hold up well (not a very scientific study, but it was our observation). I agree that the bunks might be tough as the little ones get older. The oldest, who is 16 and weighs in at 138, sleeps on the bottom and it works, but it's not a palace. There are some really nice TT's with slides that have a double sized bunk on the bottom. We just could not pull the extra weight of the trailers with slides and extras. Our travel trailer weighs in at somewhere around 6,500 pounds the way we load it. I keep the tanks empty when travelling (just a few gallons of fresh water to work the sink and toilet while moving) because we are getting close to our maximum Gross Combined Weight. The truck tows it fine, and I don't feel nervous or anything, I just know that it's not good to be that close to the towing capacity for too long. It has AC, which we've only used at the beach once, and the kitchen layout was what sold Nancy on the trailer (she loves to cook, and I love to eat!). It's been the perfect match for our various trips, but the 29 foot length has limited our options on some of the older state park campgrounds in our area.
We have an acre of land with enough room to park what I want either out back or in the driveway if getting ready for an upcoming trip, so the cost for storage was not an issue. Good luck and have fun hitting the RV shows. There should be some good deals coming along with the gas/diesel prices going up!
Happy Camping.
