Driving an A will not be an issue. I' a retired crane operator. Yrs of driving a 165T crane, 90'L 12'W, 145K back & forth between Phx & LV plus 10+ yrs owning 3 semi's. I'm single and 99% of the time I go alone so the size isn't an issue. The only thing is the tank size, boondocking with those small tanks will not work. May just stay with what I have. My 5er toyhauler has 122 fresh, 43 blk, 40 gry. the fuel station is a big plus over cans on the small trailer with the buggie.
I was just thinking about later on in life when I may stop the trail riding a C would do the job. What I see is the price is about the same A or C in the used market. That is a surprise.
