Thanks.

The complications with the ProPex are related to installation on my
Scamp 16 (layout 4). These issues might be different on different trailers and in any case could be overcome. In fact, it is such a nice heater it might be worth the extra effort, it is just adding more complications than I want to tackle. I’m sure that some will think I am getting bogged down in details of little concern but this is how I see it…
The ProPex unit is designed so that a primary installation option is under-floor however there is no room under my trailer for it underneath except at the back, and I do not want to add any more
weight at the back since I already have to make an effort to not go under 10% tongue
weight. Plus I would have to remove a sewer hose holder that I mounted under the rear floor.
Installation in the lower side cabinet (perpendicular to the camper’s body and under the stove in my case) would probably not leave enough room for ducting. It also makes it very difficult to access the gas connection. I could use it without any duct but that creates more noise and less efficiency since the cold air intake is right next to the hot air output.
The exhaust flue must be between .75 and 2 meters and should terminate at the outside of the trailer and not within specified distances from
windows, etc. This is so that exhaust gas does not enter the camper. The exhaust flue can get near 300 degrees heater and should not be run in contact with the wood floor or close to any area that would be damaged by high heat. All this is do-able, just more difficult and ProPex does not even publish safe clearances for the flue and duct so it’s a bit of a gamble. The output duct should not be in direct contact with anything that could be damaged by heat, especially near the heater. The heater also requires about one inch clearance whereas the Atwood is a zero-clearance appliance, making the install simpler.
