I have a 04 Minnie Winnie, I want to check out the heater but I'm not sure how to open the exterior panel/door. Do I need to remove the chrome exhaust/intake grill ? I took the 4 screws off the bottom already and it's a little loose but not opening. I also put some lube on the hinges.
If I need to remove the grill, do I need a special caulk for behind it ? or will proflex be ok ?
