Have any of you done your own undercoating and what product did you use? Looks like it would be fairly easy unless you just didn't need it due to being continually bathed in oil. Mine could use it under the floor pan and bed.

I can vouch for MonstaLiner. My truck is covered in it. No matter what product you use, it's only as good as the surface prep underneath the product.

Thanks for the reply, In had thought about using bedliner. The plan is degrease, pressure wash, sand a couple of surface rust areas, por-15 those areas and undercoat. Did you spray, roll, or brush on the liner underneath? What 's your mpg with the 10speed?

I haven't used it as an undercoating yet, but I plan to.

The mileage on the 6.2 and 10 speed is unreal. Better than the Cummins, with or without my camper. I'll have to get back to you with numbers, not sure what I have recorded.
