I’ve got a 10-2 EXCD, as with all campers there are some small things to modify and improve but overall I believe it to be the best you can get, in terms of durability, leak resistance, and layout.
First thing to do is install a power on/off switch for the wireless HappiJac control unit in the left rear compartment. It comes wired “on”’at all times, no switch.
There are numerous reports of HappJacs randomly operating and sometimes tipping a camper over.
My only big complaint is Northern Lite’s use of HappiJacs, for many other reasons than just that one, which is super easy to solve.
