Cushion between the cabover and Truck

I have used a doughnut around the window for 21 years on my rig and would not do without for the reasons mentioned and more. I have noticed that many new truck campers don't have suitable windows on the front but if yours does I would use it. That is one feature I would look for if buying a new camper. I also use a pad between the cabover and the cab of the truck. I started with a magnetic sheet I got from a sign shop and fotunately had access to a large amount of suitable foam that I glued to the magnetic sheet to fill the gap. The magnetic sheet does not slip on the truck so there is no abrasion to the paint. I have not noticed any wear on the fiberglass of the cab over. The main function of this was to reduce frame flex so I put is near the "A" post where the roof is sturdier but it does still oil can some. My truck is a '91 F250 Supercab and I have a 12' Caribou camper. Between the age and length of the truck and the weight and length of the camper I was getting enough frame flex to allow the front of the cabover to bob up and down an inch or two on big bumps. All of the new trucks have much stiffer frames and even my truck did not flex so much with the 10' camper I started with. The pad did reduce frame flex and improve the ride but I would not mess with it if I did not see a lot of movement between the cab and the camper. However, it does keep a lot of wind and rain away from the boot and open windows, making that work much better.

The best thing I did for the ride loaded and empty was to put on some Ranch 9000 adjustable shocks. I just wish that I had done that 20 years earlier.
