Spacer under camper - manufacturer "approved" solution?

I had to raise my camper 1-1/2" so I just used a couple of 3/4" pieces of OSB that I painted. I would prefer something lighter like dense foam, but the OSB has worked well.

The camper bottom is sprayed with bed liner from the factory and in well over 12K miles, there has never been any movement on the platform.

I certainly do see your reason for concern and the potential problem. As a precautionary measure, I will add a ledge of some sort.

Even with kiln dried material, weight adds up very fast.

Thanks for all of the replies everyone - Jeffrey, yours in particular looks super clean - nice work - did you build the side storage boxes yourself?

I just called Adventurer/EagleCap and they pretty much didn't have any specific info on the '07 since the company has changed hands so many times. His recommendation was to support the entire floor since that's the way it's designed, which makes sense I guess. Maybe a "composite" approach might make it light and strong - like maybe 1" of high density foam + a sheet of 3/4" ply or something ...

I left those "wings" in front of the rear wheel wells which insures that it will not slip backwards.

With platforms in general, I prefer kiln dried lumber, but only because it is lighter in weight, making it easier to remove the platform. Strength or rot is not an issue with any lumber for this application.

I used 2x4’s on edge to raise mine :



When I enclosed the base I ripped the 2x4’s down to 3" and added 1/2" plywood on the bottom :

Five 2x6's spaced evenly cover with a sheet of 1" plywood and then a rubber bed mat. Fitted it with wings before and after the wheel wells, leave it all year long.

Already have rubber mat, and the 1.5" from the 2x6's I've got in there now are bare minimum. I was thinking about attaching treated 2x4's or 2x6's around the perimeter of the bottom of the camper - just not exactly sure where the main structure is supported. I would consider the foam board idea, but this thing already has pretty variable CG due to the solders and tank locations, so I'm not 100% on using something that might compress asymmetrically.

How much do you need to raise it up?
