Newbee question for long timeRVer's

Like a lot of motor home owners, we migrated from travel trailers. Four of them over a 12 year period. They all kept getting bigger. In 2005 we traded our truck and trailer for a 1999 34 foot motorhome. Put 20K miles on it (still working, retirement to come). We did a complete refresh of the interior, flooring and furniture. Took it in for some minor service work and walked out with our current 2009 37 foot motor home. For us, the price was right on the 2009, they were giving us top dollar for the 1999, and it will be paid for shortly after we retire. But, I think you should rent a unit first just so you have a little more information to make a decision with.
