Same here we went from 25 foot wilderness travel trailer to full time in 30 foot Cougar 5er to 36 foot Hitchhiker to our current 40 foot Pinnacle and a 25 foot Winnebago travel trailer for camping. When we retire we will do the opposite of most people and sell the RV to settle down on our property in Idaho.We have an F350 diesel and pull a 5th wheel. I actually do all the driving, hubby navigates! LOL! I plan out our trips and book RV/national/state parks/etc well in advance. Since most places have only a 24 hr cancellation policy, adjusting our schedule during the trips is generally an easy matter of leaving a day early, staying a day or so longer, or re-routing. I pick locations based on where we want to go and what we want to do. Trips range from 3 weeks to a 3 month drive we made to Alaska and back!
We much prefer a 5th wheel, because we can disconnect and then run around in our 4 wheel drive truck. I've driven in 50 mph winds and the 5th wheel was still straight and easy to pull. When trucks pass, you get get the "sucking" feeling of the 5th wheel being pushed around by the gusts of wind. In 2019 we drove from Tennessee to the northern coast of Newfoundland. GREAT trip. We had solar panels put on the roof to take advantage of solar power.
Lots of great advice in earlier threads. I'll emphasize.... don't get something too big, especially if you anticipate BLM type camping. We seldom camp without electric....but that has never meant that we couldn't find a place to stay in a location we had chosen.
Oh....and we travel with our dog. He is a great traveler and enjoys meeting and playing with oother dogs.
While diesel fuel is more expensive, you will get much better gas mileage (and power, as Steve alluded to!) than using a gasoline tow vehicle. We did NOT want a dually and even in 50 mpg winds have not had a problem towing our 41' 5th wheel with our 4 wheel ,short bed F350. However, we got a SuperGlide 5h wheel hitch. When making a 90° turn, the 5th wheel slides back (way from the truck cab back window!!!) and when I straighten out, the hitch pulls the 5th wheel back up into position. Love the SuperGlide hitch.
BTW - we previously had a 35' 5th wheel and I would have stuck with that length again, except we couldn't find what we wanted in 35 footer. The 41' Grand Design Solitude 5th wheel has been a dream and we don't regret getting it.
We started out with a really (too) small trailer....and after a couple of years, moved up to a 35' 5th wheel. We used that for 8 years, then traded it in on our current 41' 5th wheel.
Too small isn’t fun especially with dogs. We spent last winter working out of state in our 25 footer and it was ok with one doggy.
40 foot is too big for small trips, imo.
