I had an Escalade before we got out of camping...either an '05 or an '06, used it through late 2009.
Great unit. Never had a bit of a problem with it other than with the Norcold fridge/freezer...spent a few weeks trying to get Norcold to address that issue, then called KZ for help. KZ promised to get back to me (and did) but the next thing, I knew was that a local repair shop was calling and offering appointment times to swap out a complete new fridge.
Our Escalade was 36' per model number...about 40' all told from the front of the cap to the rear. Big- A** unit. We switched from a Cougar TT (about a 30' model) to the Escalade....if you're making a similar switch, you'll be a bit more limited in the places you can stay. Keep in mind that Escalade's are heavy. We typically operated near the 16,000 range (for the Escalade) when loaded for use....of course, with all the room in it, we threw everything we could think of in the Escalade.
Pulled it with an F350 6.0 with Tow Boss.
