I use mineral oil in all the 6v batteries. I check levels ever other month or so. I have a 4 stage charger.
I have a motion light that attaches to the side of the RV with a magnet. Does a nice job of illuminating the entry door at night. Must remember to stow it while underway.
Unlike TwoGypsies I make reservations at most places well in advance. I want to stay at the best places and have never stayed at a Walmart. Traveling in a 40 footer towing it makes life easier knowing I have a place for the night where I want to be. The downside, I'm constrained by my schedule but I've learned how long we want to stay at most places and plan it. YMMV
Excited to try our new fire pit.
Goggle My Maps displayed on a tablet showing our driving route for the day with all the TA truck stops on an overlay. TA gives the best EFS fuel prices. A nice backup to our GPS.
Grill Mats; keeps the grill clean and the mats are easy to clean. We do a lot of grilling.
TPMS, don't leave home without it.
Awning LED lights installed on the side of the coach just below the awning. Illuminates the passenger outside area nicely with different colors. My coach was made before this became a common install.
My checklists, I use them without fail and have never forgotten to do anything.
