Leah welcome. In 2007 we bought a 1993 MH on a 1992 Chevy P30 chassis with the 454 TBI gas engine. The kids at 9 asked for a MH so when it needed fixing they questioned their request after learning more about auto repair than they expected. :)
In 2011 we took a 8000 mile 31 day trip to the the Pacific Ocean and it ran really well there and back. We paid $7995 cash for it and had another $5000 cash in it by the time we did the trip and did all of the house repairs ourselves and some of the chassis repairs.
The wife said it was not her idea and did not help us work on it but then it was a class shop project for the kids and I teach the home and auto repair classes.
The point is it will cost about $5000 to rehab a 20 year old truck and the house on its back over the next few years on average if the engine and transmission are internally in good condition at the start.
There is nothing wrong with buying a MH out of its prime by 10 years and they are relative easy to work on in the drive way. It just takes a few years and short trips are best at first.
Actually I expected our MH might be nothing more than an $8K playhouse for the kids parked in the drive way but that sounded cool to a nine year old boy and girl. :)
Hang in there and in time you will have it as good as a $15K MH and for a lot less. We had made a run into town in the MH as a working on it reward like four years ago and my son was co-pilot coming home when he really floored me by saying, " When we go to the Grand Canyon since we have our tools in the MH if it breaks we can just get it off the road and repair it ourselves."
That was the day I knew our MH purchase was worth every penny and the repair costs.
Others have posted some trouble shooting tips to learn if you have a fuel or spark issue or a combo of the two. Hang in there.
