Thinking about going the Echo route as well but I am sure I'll check it every chance I get. Found this as an possible option - it ain't pretty but would ease the worry? (YT video):

Just picked up my Gladiator so no pics yet with it. This model is really popular for mods - see quite a few Jeep (Gladiator) owners on the FB forum. It's an Intech Flyer Pursue - all aluminum welded frame - I've got the AC, Heat and Maxxair fan and slideout stove\frig combo. Lots of conversions...
I'm picking up at the same dealership - original was 7/22 then moved to 8/24 last week.
Salesman just called to tell me it has arrived! Maybe same for you?
