Lost Front Section of Underbelly Insulation

[Tenbrooks]

On a recent trip (Aug., 2020) we made from Texas to Montana we lost the front section of the underbelly plastic sheathing and all the insulation in that area on our 2019 40KSSB4. I found the problem at the first diesel fill up we made somewhere past Wichita Falls, TX when I discovered insulation wrapped around the front landing gear. Problem was attributed to the fact that DRV doesn't use washers when installing the sheathing panels under the wool insulation which will tear through the plastic sheathing. They merely use a screw with a small flange on the screw. On our return trip we stopped at Rolling Retreats and had them repair the lost insulation. They also removed all the screws holding the underbelly sheathing strips and replaced them with larger screws + washers. They told us, this practice is a routine action they take for all new DRV's they sell. How was I to know? You may want to look at the underbelly of your rig and see if the screws are pulling through the plastic sheathing sections. We were lucky to find the problem so fast and have RR fix it.
