I am a 5th wheel person so a little biased. But I have towed many travel trailers and boats and nothing compares with the ease of towing a 5th wheel. Hardly know it is there, no pulling the truck around and feeling like the tail wagging the dog....plus very easy to hitch up one person can do it, since you can see the hitch.
My other primary reason for going with the 5th wheel was a separate bedroom serving no other purpose, up over the bed of the truck out of the way and I don't need to fold out a couch or drop a dinette before going to bed.
Get a 5er with a slide and you will have a full time RV and easy to pull. 2500 will tow a bunch of 5th wheel and a 3500 will tow even more!
Good Luck in your search...
