Op, remove the rims with the flat tires and take them to the tire shop, have them replaced and aired up, reinstall them on the MH. You do not need to pay someone to do grunt work. It you cannot do this, I'm afraid that you are in way over you heads.
IF a raccoon was in the MH, you have a real breach of the MH somewhere, and must find and fix it quick. Someone mentioned possible wiring problems and to remove the engine cover. Removing the entire engine cover will be a job. First pull the rug up around the base of the cover, and back about 8". Remove all of the staples that are come through the rug, as these will scratch, cut, puncture you. Since you have had rodents inside, the last thing you want is an injury that could infect you. There are screws holding down nailing strips around the base, remove and there will be more under the strips holding down the cover. On Fleetwood's, the engine cover has a flange around the base, but it is not very heave and will break/split easily. This flange is also sealed to the floor with a urethane glue. To get it started, use a flat spring bar to drive under the flange. Work around the cover and use flat blade screwdrivers, or wedges to maintain pressure upwards. I would use a multi-tool with a cutter blade to work around the cover base. There will be screws in the hump, against the firewall also, at random places. Try not to break or crack the engine cover as this will just to the costs and be a big delay, as it will have to be made for you. Hopefully the drivetrain wiring will be intact, and you will not need to remove the cover at this time.
Good luck, and if you need more advice, we have more advice than good sense. LOL
