I have a SRW and I was in your same shoes about a year ago. A little different situation because I use mine for family camping and hunting so I wanted to haul my 4 wheeler in it as well. I eventually just went with a 29ft bumper pull with super slide and put my 4 wheelers in the bed on a deck for hunt trips.
I'm a safety freak so I bought the best sway/weight distribution hitch you can buy and I feel I made the right decision. I hate not having the use of my bed with a 5th wheel and toy haulers are so damn expensive.
