Did it on our MH, measured, measured again, drilled 1 inch hole to triple check location and clearance of wires, cut hole and made it accessible for future reference. Year later I needed to check fuel gauge wiring and used it. We can roll the carpet back from the doorway, cut the padding, then drill the floor, multi tool or shallow depth jigsaw will do to make a trapdoor.
Will look for pictures, but if you use the handle of door to electric panel area and drill about 6 inches toward front of MH you will have the right location.
