Cglenn Posted May 31, 2022 Share Posted May 31, 2022 (edited) Looking for ideas to seal up around the punched bed holes for the 5wp. I will be installing a retrax cover so I want to attempt to seal up avenues for dust/dirt/water etc to enter the bed and these oversized punched holes are prime candidates. I will also be installing a spray liner as well after the holes are sealed. I am thinking about a urethane caulking which should allow the bed liner to adhere. Ideas and suggestions needed. Thank you Edited May 31, 2022 by Cglenn Quote Link to comment Share on other sites More sharing options...
bshort Posted May 31, 2022 Share Posted May 31, 2022 Sell the truck and buy a car? Can't see how one can completely eliminate dust and water back there. It will get past any tailgate seal as well. 1 Quote Link to comment Share on other sites More sharing options...

Thanks for taking time to respond with such a useful suggestion to seek the truck and buy a car. i understand that nothing will completely prevent dust and water but it is about minimizing points of entry.

NoPistons Posted May 31, 2022 Share Posted May 31, 2022 Get the bed liner sprayed before sealing the holes and use a black silicone based sealant around the 5th prep stubs. It was recommended to me that a vent tube be installed between the cab vent and the box header panel. Having the cabin fan on medium or higher, keeps the bed pressurized and stops the majority of the dust. I did not do this option as I often have my bed open and used for truck things. For my truck use, dust is par for the course. Quote Link to comment Share on other sites More sharing options...
Ford truck guy Posted May 31, 2022 Share Posted May 31, 2022 IF it is/was factory installed 5WP they have rubber/plastic cover that POP into the hole to prevent water from entering.. Since the 5th Wheel prep has not changed, you COULD go with these.... Quote Link to comment Share on other sites More sharing options...

If not, I don't know how big the gaps are because I don't have my truck yet, but maybe some short strips of P shaped window foam. Glued on the puck side if you want. One caution, if you seal everything as much as you can but of course you can't get it all, those holes also allow water to go out.

Robin Hood Posted June 1, 2022 Share Posted June 1, 2022 If you are not planning to use the 5th wheel prep, then install the plugs or cover with almost anything and have the bedliner sprayed over it. Quote Link to comment Share on other sites More sharing options...
traveldawg Posted June 2, 2022 Share Posted June 2, 2022 I used some LockTite Poly caulk for the seams. I used a half piece of pipe insulation for the sides of the tailgate and some foam weather-stripping for the bottom of the tailgate. I have a Roll-n-Lock cover. I'm probably 90% sealed but dust is still going to get in. I think you'd need one of those hinged solid fiberglass tops to stay any dryer but it kind of defeats the purpose of a truck (as does a bed rug - there is an oxymoron... bed rug...). 1 Quote Link to comment Share on other sites More sharing options...
