Ramps Used for Parking
When I brought our new Monaco Knight home I simply backed up over the curb and into the prepared parking place. I did this twice before discovering that the engine oil-pan had been seriously damaged when it dragged across the sidewalk.
Just before the rear wheels were in the gutter and before rising up over the curb, the engine lowered down to the sidewalk crushing the bottom of the oil-pan. Then as the motorhome moved back to the curb, a bit of the thickness of the metal on the bottom of the oil-pan was ground off leaving the crushed metal thinner.
Below can be seen the solution I came up with before moving the motorhome again. The ramps keep the rear of the motorhome up so the oil-pan doesn't lower to the sidewalk level. Once I knew no new damage would happen, I ordered a replacement oil-pan at the price of $200. Then with a new gasket kit I replaced the oil pan. I also installed a set of solid stainless steel wheels on the rear of the hitch-receiver frame to keep the back of the motorhome from dragging on steep driveways. I've felt those wheels working several times since installing them. It was money well spent.
