Hello, I am new here but having a Sprinter for two years has brought me to this forum many times. We are now also considering a larger RV in the 30-34 ft. range and comparing used vs. new.
Not much advice that I can give except after all the reading and hunting for the right rig, factory warranty or at least a thorough check by a private maintenance company is a must.
I know....driving off the lot "losses" bother me too, with a new one. There are many things to consider like Tire wear, past history of a used RV, was it sold for that reason? And what changes have been made on the new one that will gain resale value later...for instance smaller windows, decor, etc.
Our Itasca Sprinter was a year old, and we have not had any problems, it had 22,000 mi. . Regarding resale now, it drops quite a bit in the third or fourth year, so all that savings to begin with diminishes a bit.
I like the Thors line, and think they really are tops with style and buyers needs. Long term quality I do not know.
This will be an interesting post to return to. Good luck!
Oh forgot one thing, yes lower your offer on the 2013
