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

I have no problem with my 6'4" bed and my fifth wheel. I have a Pullrite SuperGlide automatic sliding hitch. I drive it just like I was driving a long bed truck. When the turns get sharper, the hitch head automatically slides back for additional clearance. The only problem with a manual slider is that you must think about it and get out to use it before you need it. The SuperGlide will set you back a few more bucks, but I think it's well worth the piece of mind. Good Luck.
