I would think Recpro does not incorporate a control for an auxillary furnace into their system for a reason and never will. The IR remote control to control the onboard thermostat and controls is a better system because everything is contained. No need to run thermostat wiring through walls or ceilings and have to work with a wall thermostat that would fail. Also can integrate into smart features to control the IR with your phone for only $40ish. They are engineered in Australia so if the need for heat in your RV or caravan is a must then the heat pump will work fine to temperatures of around 0 degrees Celsius. I imagine in Australia propane heated furnaces are overkill.

Thanks for all the info. I will be going with the Recpro replacements for both my old AC units and keep the 5 button CCC for the 2 furnaces.

Was the Recpros an easy conversion from the Penguins? Any fitment issues during installation? How did the thermostat wire up? Did you upgrade the thermostat or keep the old thermostat and the control modules from the Duo Therm AC units?

Thanks for the info Tom, I have been reading and researching like crazy. So from what you are saying is that I am stuck with Dometic because of control system having a different data link control system than other brands. I am not really interested in snaking and running the 7 wire thermostat cables to each unit. I also want to keep both furnaces under one control with the AC units. So that being said, has anyone had any experience with the different Dometic models? Which ones have been more reliable? From reading some of the forums, the Brisk has refrigerant loss issues. What about the Blizzard NXT or new Penguins?

Lots of great information on this topic. Thanks for everyone that contributed. I have a 2005 HR Endeavor 40DST with a Duotherm 13.5k in the rear (original) and a Penguin 1 13.5k in the front (replaced by original owner 8 years ago. I have a few questions. Instead of going with Dometic is there better brands that are more reliable? Has anyone tried Coleman, Advent Air, or others? Are the Penguin 2 ACs the best and most reliable from Dometic?

In my owners manual I havent found any info on the little circular on/off switch above my engine diagnostic button. Does anyone have any info on this? Will having the switch down turn off the power to the ABS and ATC? When I hook up my computer to the motorhome I only see the Cummins engine and Allison transmission. How do I get fault codes from the switch? ABS - ATC Diagnostics.pdf

I went and checked out the bags today and this is what I found on my 2005 Holiday Rambler Endeavor 40DST on the RR8R chassis. Front air bags were double convoluted Firestone 20F-2 on the bellows which is W01-358-6393 in the catalogue. The rear air bags were reversable sleeve Firestone 1T115L on the bellows. Unfortunately this bellow stamp can come in a lot of variants on page 18: I am thinking by the catalogue that I have either W01-358-8897 or W01-358-9376 I dont feel like screwing around with pulling the upper part of the bag off with that one hard access nut on inside. I guess worse case I can reduce the port to 1/4 NPT. I reached out to Rev who now sells all Monaco parts and this what they said: (what a joke on price) '05 Endeavor 40 DST Double Lobe Air Bag w/ Longer Bumper, Front, part number 10119167, $621.30 each, in stock Large Rolling Lobe Air Bag w/ Longer Bumper, Rear, part number 10109709, $831.44 each, in stock You can order parts online at revrvparts.com or call 1-800-509-3417 and speak to any representative to place your order.

Thanks for everyone's help. I went to the motorhome and crawled up in to take a picture of the alternator. d*** its tight with the intake right there... The build sheet only said it was a 160 amp with no details. The tag said Leece Neville Model 8RG2112 B Volts 12 200501 Sales No : 105-360 If anyone has the spefic part number and data for the Delco 28si that would be much appreciated. Is there any other changes that need to be done to fit it in where the Leece Neville was? Cable or connector changes? Pulley?

Does anyone know what alternator they use on the 8.9L I looking for a rebuild kit for my alternator. Thanks

I have a 2005 HR Endeavor 40DST on the RR8R chassis. Is that air bag pretty standard? I am trying to find the part number for the one I need.
