I bought this EasyStart for my Coleman Mark 3 over a year ago, hadn’t installed it yet do to a motorcycle accident. Finally recovered got on a ladder, had this thing properly installed in under 30 minutes tonight and WoW! Startup current went from over 50 amps to under 20. RV Life is going to be awesome now that I can actually use the AC. Brand new trailer and could never use it on my small Ginny. Not I can run the AC and the fridge no problem..
