I will investigate these options thoroughly and then dedicate a day to diving into what appears to be a significant project. I will post my lessons learned for future RV enthusiasts that come across this issue.Re: Milan 25RKS Trailer furnace accessBurbman you have illustrated it well. The water heater is behind the large vent. As you say it looks like some cabinet disassembly or maybe water heater removal to get that rascal out. The panel where the CO2 alarm is is too small to take it out forward. This sure looks like an application where that same furnace model with the outside panel would have been appropriate. Thanks for all your help.Re: Milan 25RKS Trailer furnace accessThanks, you guys have me half way there. My remaining challenge is how to get the furnace out from between the wall behind and the cabinet face in front in addition to the floor below and the drawer support structure and sink above above. Any additional help in this remaining portion of the puzzle will be greatly appreciated.Milan 25RKS Trailer furnace accessI am attempting to service/repair Atwood 8531 furnace mounted on the floor blow the sink against the back wall of the trailer. It is confined forward by a built in solid cabinet front with removable drawers just above the unit and below the sink but drawer framework remains that won't enable removal of the unit. I am trying to get to the electrode for troubleshooting due to lock-out approximately 5 seconds after ignition. There appears to be no access panel for the combustion area from the top. The only access from the outside is the exhaust vent, when removed you can shine a flashlight through and see a portion of the electrode. I am looking for anyone who has been here and hopefully can tell me how to solve this puzzle.
