Thanks for the suggestion. Unfortunately the way my camper is constructed, that might be a less safe location than even my compartment. I would need to bring the storage can into the camper and a leak in the wheel well area would be a disaster with the camper sitting on gas and fumes entering. There has to be a better way.
I wonder if any of the truck camper manufacturers have given this any thought. It is difficult to find a suitable exterior location on my Northstar. The area above the back bumper would be ideal but it is well occupied with a lighted license plate, stop lights, a ladder, door and a compartment for my generator. The poor construction of gas cans and the spouts does not help.
