When you do a tune up, take the time to do a compression check. That may give you some indication as to the real condition of the engine. I assume this is a new to you purchase. If so, many motorhomes sit for a long time before they are finally put up for sale. Could be the cylinders rusted and the rings are not seating very well. That may improve over time, once things get loosened up again.
