Need help with crazy ideas- LP appliance ventilation
Hey guys! I need some tech help. I have a fiberglass truck cap and due to lots of reasons I won't get into yet, I want to set it up like a travel van kinda sorta. Anyway my main two appliance issues are refrigerator and furnace ventilation. The fridge is a 3 way unit (12/120/LP) but running on 12 the whole time isn't practical, it needs to be able to run on LP also. The furnace is a small unit from a late 80's slide in truck camper and doesn't take much space. I have an extra tailgate and can mount the furnace to the gate so it vents through the gate, obviously couldn't open gate with furnace on but that's not an issue. That doesn't help with the fridge though. I haven't done any good measurements to know where the vent will line up on it, but I am kinda thinkin we don't want to vent these appliances through the bedside (ie; vents into the space between bed skins). This may not provide adequate ventilation not to mention the lack of accessibility. I will not chop up my cap and put vents in the side of it, not an option anyway due to large side windows plus I don't think the fridge vent will be able to mount that high. Any other ideas? I may have to do the furnace in tailgate as mentioned and forego the fridge for a cooler. Again constant 12V operation not really an option due to battery drain when parked.
Thanks in advance!
