possible awning/screenroom

Put it on whichever side you would use it on most. It's your camper. Just need the uninterrupted length and be aware of the height needed to clear any obstructions like range good vent, fridge vent, Windows, heater vent and hot water heater vent. One option is to mount "c" track awning rail at desired/feasible locations on both sides, get a cabana screen/privacy room type awning and use it either location. It is safer for the awning to transport it on the passenger side due to traffic wind gusts in the driver side. Those work best mounted at 7' from the ground, can be used as an awning only, screen room or full privacy room but require some modifications to work on a TC rather than the pop up campers they were designed for. We put one on a small horse trailer and also had one on a living quarters horse trailer. Opted for standard box awning on TC passenger side and ARB bag awning in the back due to ladder/door placement issues. There again, a modification was needed on the bag awning due to mounting height issue TC vs vehicle roof rack. It works well tho. Bottom line is its your decision so think on it, measure and do your homework before spending any money.
