Welcome to the GS forum. I never had a gasoline GS coach, but I have had other brands. The Ford V-10 is a very good engine and you will get around 8-9 mpg. It is probably built same way my gas coach was on a F-53 chassis.

One thing I did not like about my 36' motorhome was that some have a long over hang on the rear and tend to drag real easy on just about any dip. Best thing you can have to eliminate that is to have rear Firestone air levelers. I would add 90 lbs of air on each side and it lifts the rear end up, plus it gives you more carry capacity, and a more stable ride.
Check your tires for cracks and the DOT date stamped on the side walls. If you have been reading some of these forums you probably know already that after five years tires start to get sun rot and the side walls will show right away with small cracks all over. Sure sign for a blow out to happen.
Check records from previous owner to see if oil changes were made within the recommended mileage. Check the interior for signs of water leaks. Get on top of the roof and check the caulking to see if any cracks are visible on the caulking. Give it a good test drive. Check your slides and levelers to see if they work proper.

Then if you find that the coach is in good condition, take it out and enjoy it. We have really enjoyed ours. I bought mine new in 2003 and it has given us very good service.

But you also have to remember that a coach is just like a house except it is rolling down a highway bouncing around and you will need to adjust things. It is just part of RVing.
