I think we got the rv fever about 6 1/2 years ago. We are on our 3rd rv. We are in our early 50's and have traveled nearly 60,000 miles in our motorized rvs. Other than mounting tires on rims and balancing them, I do all of the upgrades and maintenance myself. I installed a new crate engine on our first rv. This morning I repaired the electric steps on our second rv and repacked the front wheel bearings on our new rv. Now I see why Camping World wants about $350.00 for doing it. It was like working on a dump truck. It has become my full-time job. Thanks to the internet and sites like iRV2 I can get answers to anything that comes up, and believe me, it never quits.
I'm saving a fortune by doing it all myself, but still spending a fortune and loving every minute of it!
