If I were you, I'd consider trying it the first several months with the trailer you already have. It will let you see what things look like before you commit to payments. Your 2500 will limit you to light fifth wheels. I suggest that you should consider staying at about 1500 dry pin weight. The truck is listed for more, but by the time you have a full tank of gas, hitch & the wife in the truck, that number goes way down! Although it is short on closet space, take a look at the Fox Mountain 235 fifth wheel. Built by Northwood & they don't use Lippert frames. Dry hitch is 1375. It is nicely put together and is higher quality than many of the others you will find.
