People keep pointing out service and parts. Simple matter of fact is that it is built from the same parts as a residential unit, so I fail to see where the issue is, unless, and only unless there is a control system failure that you can't find parts for.
Who cares if Coleman doesn't support it? So far the only valid issue is the rear ducting that was a known issue and can be fixed, but likely not cheap.
Also one thing that hasn't been mentioned in 2 pages is that is sure is nice to have a nice clean A/C free roof when you're installing solar. Either they are in the way or shadowing a panel.
