You can't beat a long wheel base for the safety of driving down the highway. However, when it comes to making u-turns or backing into a campsite, in a crowded CG............I often wish that I had a small SUV (just for parking).
We were at a CG called "Carmel by the River" a few years ago. I had my S10 (127" WB) at that time and I was
just able to squeak into that space with about a 16 point turn. There is
NO WAY that my Silverado (157" WB) could have gotten that trailer into that space. I now choose my campsites wisely.
I have the same issue in my parking garage (subterranean apt building garage). I used to back my TM into my space easily with my S10. Once I bought the Silverado, I had to go out and purchase an electric dolly to get the camper in my space.
