All pretty good advice. Our first & second RV were used and were a very good deal. When we looked for another we thought we would buy just what we wanted and would depend on reputation. WRONG!! The factory warranty was mostly a wasted trip. We spent 2 yrs. of hard work and +$15,000 to get what we thought we had purchased! Owning a tool & die shop we had the expertise & facilities to do the work ourselves but it was still a painful experience. Check the ads & find the unit that meets your desires, price, etc. Then get an HONEST tech to COMPLETELY inspect the whole unit before committing to a sale(the fee is well worth it). Used is always the best option, just takes longer to find the best fit. Best of luck on your new life.
