Are you planning on living in it? if so, yeas... be very careful and get a good inspection done. If it is for vacationing, mostly what needs to run right are the things you mentioned... engine, generator, stove , fridge, steps...
We bought an old Honey, and first thing we noticed running down the road was exhaust smell, so we had the exhaust manifold fepaired, then we had a problem with the wiring mice had been at work previously and the heat of running it finished the deal there, had that fixed. Then, the engine died. Like dead, well, I had already fallen in love and we had put enough into it, even though we looked again for a few months, no one responded or units got sold out on our way to go look/buy.... so we replaced the engine... basically,she ought to run a long time now! Looks aren't that important. Function is. Hope it works out for you and ya'll have a blast!
