haha, I tried that for a little while. Picked up a little used Caddy ATS RWD stick, just to try something different than a truck, even though it went against my bigger is safer thing. Man that was fun, for a while. It's downfall for me was on long drives over around 2 hours which I do frequently. I found that I was cramped in the little ****pit over time, and while it was really a fun car, on long interstate drives my head would actually hit the roof on all the bridges on Rt 80 in the East doing 75+. Not kidding. After about 10-20 head bangs I said enough and got the 300. ahhhhhh much better.
And I'm not big at 5-8 190lbs. Just is what it was.
Nothing like a true full size vehicle for comfort on longer trips. That's mostly the reason I've almost always had full sized trucks, and we still travel a lot so it's nice to be able to do so in comfort.
Rented an escalade a few years ago while in California and drove it from L.A. to S.F. Was pretty disappointed with how cramped it felt after a while, I knew it wasn't going to be as wide as my ram but it was still a let down. I bet those new grand wagoneers are good for road trips since they are based on the ram.
As for the original topic, I think overall most of the full size trucks I've ridden in have been alright, but ram has been the best for a while with the coil springs. I don't have any experience with air suspension though.
