We started out in the pop up camper realm with a Four Wheel Camper Eagle on a '99 Tacoma 4x4 extended cab 4 cylinder. Folks at another forum warned us about braking and power. We didn't have the funds to buy a full-sized truck at the time. Long story short: our load was a bit over with 2 people, dog, gear, full fuel and water tanks, etc. Airbags did help. We did have some trouble climbing Highway 20 over the Cascade Mountains. My husband has back pain and our truck rode like a truck. The main concern was when we came out of a tunnel too fast and the braking wasn't as secure as it could have been and we did some sliding. I have nothing but good comments on our Eagle and it found an owner who had a 2012 Nissan 6 cylinder. I miss it. The Tacoma is our daily driver.
We took a deep breath, said life is short and bought our 2008 F250 (Super Duty, 4x4, extended cab, diesel, off road package, series E tires, etc.). We also bought a new Hallmark Ute as hubby wanted an electric roof (bad back again) and it had more options. He is happy and that is what counts. I tend to like simple and drove the Taco/FWC and camped in it at several music festivals (great base for my photography). Our new combo is more comfortable and has more room. I am a bit hesitant at driving the Beast as I have always driven smaller trucks (Toyota since 1991). Maybe on a 2 lane backroad with no drop offs or switchbacks.
It does have a longer wheelbase but we were able to drive the Burr Trail switchbacks down a few turns then do a 5 point turnaround. Fuel mileage is worse of course. It is not as easy to stealth camp in the city. Braking is great, power to pass and to climb passes no problem. It does have a profile but we had no problems with wind driving across Wyoming on I80 last fall. It was hailing and blowing hard like it can and our only issue was trying to avoid semis with pups. I hate that freeway.
I am sure a newer small truck would give you more power and better braking. Probably more room. I noticed a difference in size from our 1984 Toyota compared to the '99.
I am glad we switched for safety and comfort reasons. I feel safer in a bigger truck and fewer people in little cars seem to try left hand turns in front of you. Unless they have a death wish and it will be more imposing when we get our replacement bumper/grill guard. We can still go just about anywhere a smaller rig can. Maybe not an infamous pass in Colorado. But, hey, the west is vast and we won't get to all the off roads. One issue was that we pay more for Washington state ferry fares due to height. I don't remember how much, maybe $10-$20?
