I'm going to replace the rusted-out bedfloor on my truck soon in shop, and I need to order some sheetmetal. What gauge should I go with? I won't have the ribs working for me like the factory floor, so I'm torn as to what thickness to use for durability. Needs to withstand stuff being back there (especially if I were to haul some scrap), but needs to not weigh a ton and cost an arm and a leg for the steel. Any ideas?
if you use straight sheetmetal you will need to add a lot more crossmembers in the bed. another option would be replacement panels or a replacement bed-both can be jy finds. but to answer your question i think 14ga would be alright, maybe 12 if you were hauling a lot back there
