Lurker1, we consigned our previous 2008 coach at Motorhomes of Texas last summer (2014). They charge an 8% fee (if they still do) and detail your coach inside and out as part of the consignment. I like the fact that they keep the coaches plugged in and the slides retracted until a buyer wants to look (no risk of slide topper damage from a quick storm).
It took 3 months for our coach to sell and everything went very smooth. All and all, we got back 49.2% of our purchase price on a 7.5 yr. old coach that we purchased new (not counting the fee), 45.3% after the fee.
MOT will pick-up your coach up for free (from their website).
Good luck,
MM.
