I bought this unit and it is a direct replacement for my RM2852 Dometic gas unit. i have been looking for years as i am tired of buying new dometic's at cost of 4 of these units. the width is exactly the same and it is only 3/4" shorter. i installed it by myself. easy to do then put wood trim around it it looks fantastic. on top of all that it has over 2 cubic feet more space than gas unit. Thanks Haier great product. you should advertise this unit to RVers.
