Wayne,
No intent here to encourage or discourage you here.... Before you buy I would be absolutely sure to exercise every single system in the coach, every switch, diesel heating system, roof air, dash air, awnings, leveling system, check that all the gauges work, faucets, holding tanks, water fill, water pump, refrigerator, cruise control, wipers, dash fan speed, every compartment door, all the 120V outlets, generator, inverter/charger, radio, Tvs, camera, age of tires, inspect the roof for cracks and condition, etc. The web may have some good checklists to start from.
If the house systems all looks good, then I would have the coach taken to a good truck center and have an inspection done of the chassis for leaks, broken shock mounts, especially inspect/fix the brake system, radiator fan, radiator condition, front end, engine for leaks. All the fluid conditions should be checked. They should be able to print out any trouble codes from the engine or transmission and check for prior work from your serial numbers.
The message here is to be sure that the coach is in excellent condition before you buy, or known issues are discovered and are corrected and not at your expense unless you agree. These are older machines and can be difficult and expensive to correct if something is missed. You get one chance to here to really determine if this motorhome is worthy enough for you to purchase or to take a pass and move on. There are many coaches on the market, many have issues, many are good, you just have to be sure you do your homework and know what you are buying.
Our motorhome only has the two seatbelts also.
