Howdy, My wife and I (55 and 56) are investigating the RV lifestyle in an A-class diesel pusher as a semi-retirement option since my work can carry me all over the country if I let it, but at present she works a normal job. We obviously see the romance of the open road but we want to find out about the harder parts of the experience. The stuff that doesn't get put in the advertisements for motor homes! How does this dump station thing work? Is it as objectionable as my wife and my imagination might make it? What's the real dirty job? How much true travel cost can I expect to incur driving across country. What if a tire goes? How relliable are the various mechanical systems that make this truck a home? What's the weak link? Have technological advances made buying an older motor home a risky or unwise choice or can I expect to purchase an older vehicle with success? Are these monsters mostly expected to be housed in RV resorts or can you reasonably take it to out-of-the-way campgrounds and such? As a former automobile mechanic and reasonably mechanically-inclined human, can I maintain it myself? Got a load of questions but I have left plenty of time for research as there is no rush but any info that will give me a more reasonable, realistic view will be appreciated. Thanks for your input.
