The problem: You are limited with the truck you have. You lack payload . I think its not such a good idea to try to tow a 3800# boat and a hardside camper with your truck .
Just a thought : If you plan to use it in Colorado , are there any DMV restrictions with camper/trucks and weights , i don't know. If the DMV is involved, they might want you to be able to stop the rig while its still in Colorado and not Kansas. :E
The 835 is about 3000# plus and i think its a LB model.
By the time you spend the money on beefing it up with a spring pack and all the other mods, you would better off looking for a good used 350/3500 in a LB truck.
You'll widen your camper options . You can always put a SB camper on a LB truck, it does NOT change the COG, plus you gain room between the camper and cab to store things . It also will add some weight to the front axle, which is good.
If you keep the truck you have :
If it were me, i would be looking for a SB pop up camper. You have to add about 1000# to any posted dry weight, for camper options and your personal stuff.
As an example , look up pop up specs : the site shows weights of options too .
http://www.northstarcampers.com/835 vs. 915 good info I think the 835 was for a LB truck ?
If that is true , if you have a SB , the COG might be in a different place in the bed. You want the COG to be in front of the rear axle.
You are going to have add mods to your truck and that adds up to weight . The more mods you add the less payload you have .
Truck mods: air bags, sway bars, stable loads, rancho 9000 shocks, the list can go on .
The 835 does not have tail lights , it was made so you could tow directly to the hitch w/o using an extention, it was designed to sit flush with the rear truck bumper.
That posted weight is a dry weight . There is no industry standard regarding dry weights . Most of the time, the MFG. weighs a unit w/o any options. The 835 will tip the scale at 3000# plus .
Its a little tight on storage as well. Only has one 20# propane tank and i dont you have room for an extra battery unless you add in the trucks bed in front of the wheel well, then run heavy wire.
Weigh your truck and see what payload you have ! Then only you can decide whats best and how YOU are going to feel driving it . Its your safety as well the other people who are driving on the same public highway as you .
