Thinking about some of the questions raised, I sent an e-mail to Grant at Bigfoot for his comment on the compartments. This is what he had to say...
"Thanks for the feedback.
"The compartment is in the same locations be we have done a few things to assist with the bond ans seal of the compartment. We use a special adhesive to bind the foam to the propane enclosure. We then use a second sealant which bonds to the door and enclosure which makes the entire install much better than ever. Hard to move this (propane compartment) in a camper as it takes up so much space. Location is really dependant on floorplan layout."
