My advice.... Get the trailer you want, then modify the van to make it work. If you have a semi-float, you may have to upgrade to a full float, or even do a dually conversion of the hitch weight causes you do go over axle ratings. Remember, published tow ratings don't matter to DOT, only axle and tire ratings.
An RB van will help you stay under your rear axle and tire ratings, but a good hitch can help, or you can do the axle modifications. But you are much more likely to find a full-float in an EB wagon. As far as diesel vs gas.... Ford offered the V10 with higher ratings with lower axle ratios, but the diesel is easier to squeeze more power out of because it has a turbo. However, once you start boosting the diesel, cooling can be an issue, especially EGTs on the 7.3L.
My Weekend warrior was 41' long (custom build, with slide and 6" lift) and topped 18,000 pounds loaded. Hitch weight was 3200 pounds if the tanks were all full and there was no vehicle in the garage. I had to fabricate my own receiver (P.E. approved the design and fab). It was already a dually at that point because even my old 30' trailer would put me over the ratings of my rear tires.
I also switched to 4.56 gears because even with 4.30 gears I wanted just a little more torque (and the 4.30 gears are not as strong because they only come in a D60 size but the 4.56 gears allowed me to up to the D70 carrier.
