We bought a 2008 model ( really a 2007 Ford) but I don't know anything about the 2006. The price had dropped closer to our range I guess because of the gas cost now and only us fols are buying
We have used it 3 times and now back to the dealer for some fix up..the usual Concertone stuff etc. So far not much we haven't liked and so far my fear of leaks has fortunately not happened . We got an optional small inverter and it is installed bizarrely under the front seat so tyou have to get on your knees to find the off switch- we thought about getting a remote switch installed that someone on the board here suggested but we are afraid it might void our warranty...I guess we'll continue to crawl around.
I try to check in about once a week--not too many Lexington owners here--keep posting and good luck!
