Our swamp cooler was incomplete so we replaced it with a fantastic fan. Note that the swamp cooler is always open to outside air, can't close it like a standard roof vent or fantastic fan. Wasps & bees like to make nests in it. We have extended our counter top by using the tops of wood snack trays on shelf brackets at each end of the existing counter. Removed original ice box, made a platform in that area, and installed a dorm fridge. Had to slightly enlarge the opening. New power converter and all new wiring, both 110 & 12 volt to allow for the fridge, electric heater, additional
lights, TV, coffee pot, toaster. We've made many modifications, still working on it. How are your
windows, any
leaks. Look in all the storage areas with the liners out, if you have them,
leaks from
windows, marker or
tail lights, and seam flaws will show up there. Wind driven rain can enter the stove vent louvers and drip on to the stove.
Leaks can occur at the
solar panel. I mention all this as leaks have been the most frustrating repairs I've had to do, and they can be quite difficult to locate. If you want to attach something to the wall, one option is make a hole and use those plastic inserts like
Uhaul used originally for the curtain rods. Note that the space between the inner and outer shell varies throughout the trailer, so be careful if you drill or insert screws. A previous owner used too long screws in a couple places on ours and they went right through the outer shell.
