I think I am going to up that on my priority list for mine, am tired of trying to back that damn thing up, it has a mind of its own.Just ordered new Grizzly 40qt cooler. Getting an early start on gearing up for 2018 Overland season.
Next is to start planning additional electrical.
- extend tongue by 12-18"
- add the max coupler
One day I will get around to getting a bigger tongue box so I can get a bigger battery, inverter & charger/charge/controller all in there. I did break down and invested in a Generator after years of resisting it recently and it has already came in handy on a 5 day trip into deep woods so my solar setup was all but useless.
As for heating the tent I'd say either an electric blanket or one of the Mr Heater Buddy's, just get a carbon monoxide alarm if you go the heater route.
