Well,
without knowing the weights of the camper, trailer (loaded) and actual weight of the truck, its hard to make an enlightened comment, but here goes;
- the camper itself is probably light and not a huge deal to haul by itself, the two areas where it will have the biggest impact is 1) center of gravity of the load on the truck and 2) the effect it has on towing your trailer i. e. the length of hitch extension required.
- I would weight the truck and get the trailer gross weight and tongue weight.
- Then I would get the manufacturers weight on the camper and check the center of gravity. You don't want the center of gravity to be too far behind the axle. My last two trucks came with a camper loading sheet that indicates an acceptable "zone" for the Cof G.
- Check the camper weight, truck weight and trailer tongue weight vs. your 8800 GVWR to see if you are going to be overloaded. You will need at least 500lbs extra capacity for gear etc. in the camper.
- Finally, you need to consider the length of the extension that you might require and its effect on your hitch capacity. The longer the extension, the less weight capacity it has. You can increase this capacity by using a weight distributing hitch. If you are over the load capacity of the hitch using the extension that you need, you can replace the factory hitch with a "class V" hitch like the Reese Titan or Superhitch.
Hope this helps,
Dave
