Compatibility With My RV and Accessories
Before I buy, I make sure the box is compatible with my RV plug type and any accessories I use. I check the outlet configuration, amperage rating, and whether it can support my setup without issues. This helps me avoid buying a box that looks right but doesn’t actually fit my needs.
Convenience Features I Appreciate
I like little features that make life easier, such as a locking cover, indicator lights, extra outlet space, or a compact design. If the box is easy to access and use, it makes my RV routine much more convenient. I also appreciate a clean layout that doesn’t feel cramped when I’m plugging in.
