I think you made good choices on both the 3295RK and F250. We have the same combination although our 3295RK is a 2003 model. If you have a 2005 or 2006 F250 then it has far more towing capability than earlier models, including much larger brakes, heavier frame and suspension. As HamRad said, the 3295RK has a heavy pinweight. If your F250 has the Camper Package in addition to the tow package then you have the same springs as the F350. Ours does not have the camper package so does not have the extra leaf in the springs. We added airbags as we did have about an inch of sag. It's not very noticeable but I did notice it since our prior tow vehicle was the F350, 2003 vintage, and ran level with the 3295RK in tow.
Good luck with them. We really like our 3295RK for it's homey feel. Much more like a small apartment, in our opinion. One thing you might consider... several of us have swapped the locations of the dining table and the easy chair. It sounds strange but works very well for comfort and being able to talk without straining the neck. Whatever works for you, of course.
This is what it looks like although we've since moved the end table to between couch and chair:
