I purchased a 95 Thor Manor last year for $12K, put another $3K into it replacing the house batteries, fixing the furnace, oil change, lube, 2 new front tires, etc. and I lived and traveled all over the USA from Alberta, Canada for 6 months before returning home again. Absolutely no problems at all and am planning on doing the same this winter again. No repairs needed. I had it all checked thoroughly by a mechanic before leaving last fall and will do the same this fall, but don't expect any surprises. The biggest thing is how well the previous owner maintained it. Preventive maintenance is key. The one I bought had all the maintenance records and the PO was a handyman, so there was nothing that had to be done to it. The only reason they sold it was because he had a heart attack and could no longer travel. Keep looking and you will find the right deal. I took about 6 months of looking before finding this one.
