There is a lot of difference in the campers, BUT there is also a lot of difference in trucks by the year too.
Likely the most important question is, what year is the truck, and what engine does it have? Certainly, there are upgrades with trucks that help carry the load safer, things like 19.5 tires, Rancho shocks, sway bars and Stable-loads.
Both campers are big and heavy, and both are carried by F350 duallies in this forum, but from experience carrying a lot more on a SRW than I should have, the truck is really the determining factor.
You will likely be around 5000 pounds in the back. Lot's to think about.
