Yes, she's old but she's a keeper

Lots of good engine suggestions. A friend also said to run some Marvel Mystery oil through her and see if that doesn't do the trick. Not sure on the ratio to gas the Mystery oil should be and since the oil girl has a 100 gallon gas tank and the gauge doesn't work, I guess I'll do it when I fill up (with high octane gas of course). Still, before that I will take off the air cleaner cover and check for sparks (Thanks Executive). It's probably not a bad idea to just give her a once over like oil change, check all belts, wires, hoses and a tune-up. The title says she's got 9 million miles so who knows how many miles she really has on her. According to the little map on the side by the door, she's been in every state west of the Mississippi (which might explain why she has no rust).

Any advice on redoing the interior would be welcome too. How to make a RV without slides look as big as an RV with slides in proving challenging.
