What are people putting around the tanks to protect from abrasion? Also, can the tanks be mounted to the floor supports safely or should I really Mount to the frame rails. Ive already put my subfloor down but seems the easiest way would be the bolts through the floor. I don't have welding experience or a welder and have limited space under the bus to mount my Grey tank and propane tanks due to the nice storage compartments.
Driver side has this space
Space between storage compartments is Only 32in so I would need a box type tank.
Ironically my 100 gal freshwater tank is a good fit to go in that space between the storage compartments and I could bolt that to the frame rails but I don't know how rugged those tanks are.
