Might be worth doing a little junkyard diving like I did for a higher rated rear axle to give you a little extra wiggle room, it'll extend the service life of your bearings and their races. The added bonus of larger brakes didn't hurt either.
On the campers, the newer they are, the heavier they tend to be because of the extra features, filon (Its very heavy), slides etc....
Anything longer than the specialized short box 9' units is going to have too much overhang with a short bed truck.
When you get up towards the 9 1/2 - 10 ft range, you can safely plan on a dry weight of around 3000-3200lbs or somewhat close there in, and around 4000-4200 fully decked out with all your gear, full tanks etc....
The rear Axle rating for F250 around those years is:
Visteon web site it states 9750 lbs
The rear axle rating is limited on the SRW by the tire rating,
if you have 235/85 R16E's you have 3042 lbs x 2 = 6084
265/85 R16E's are 3415 x 2 = 6830
the dually tires would be 2778 x 4 = 11,112
The rating of the actual axle is 9750 lbs.
So there is quite a bit of margin for the actual axle itself..

Those Fords had a much bigger axle, my 3/4 ton had a D60 on it originally that I replaced with a D70HD off a motorhome chassis.
