I looked his truck over the other day. We commiserated about the usual difficulties of truck belly pans, the accumulation of dirt, rocks, water which becomes ice that never melts for 2 months and tears things off. The usual
For example, My ex-logging truck has 30 pounds of dirt on the top of the tank I have yet to remove. It got up there as dust, got glued down and is now wrapped around important things like wiring and fuel lines
My thoughts are to leave the bumper on and figure out a pan that will let stuff go. I was thinking something like the louvered covers on an 80's camaro rear window. sheet metal with big vents that you can hose out at the car wash, that still calm that progression across the bottom. I think it will work, it is just figuring out a way that is cost effective and durable.
