Advice needed -- will I regret a shortbed w/ 43' trailer?

As others have mentioned be sure you have enough payload and beware many short beds have small 26 gallon fuel tanks

My Megacab shortbed has a 35 gal tank.

I think whether or not you need the long bed depends on the front cap / front end design of the 5er. I am ok to about 85* turning with mine. No slider hitch or anything else fancy.
