It appears to me that there are a number of different kinds of rear suspensions on big trucks; traditional leaf springs and some kind of air suspension. Can someone point me to an article or link that explains the difference and possibly the pros and cons.

I'm interested in a HDT conversion to pull my race trailer and would find it helpful if I could raise the back of the truck to lift the front of the trailer up to make getting the low riding race car in and out of the trailer.

Thanks for the help! Dick
