....Dometic is a good unite I use them on top of my trailer with an inside apartment chiller unite if I need to really cool down.....my over head unites coat $500 each and the apartment unite is $300 I dont have the ocst of the under side unite but I believe it is $1700 plus labor/install and a freon charge.....geofkaye

Geof,
The Tundra unit I put in was about $4,000. but it came with freon and quick connect lines. It was pricey but it was exactly what I was looking for and was the perfect size....I don't remember the cost of the units on the roof on my conversion but I doubt I payed as little as you did...maybe next time I can get them from you or your source.....
