The protective underbelly cover is attached with screws into the frame of the 299mp you cannot staple it back on. Also under the front part of the garage floor is the fresh water holding tank and under the middle part of the floor is the 30 gal. Gas tank. You really should remove the cover to make sure you don't damage either of these. You don't have to remove the entire cover....you can remove the screws from part of it and cut the cover to move it out of the way. They make a wide tape especially for taping the cover back together. You can buy the tape at your rv dealer.
