We replaced our 4 door RV refrig. with a side by side Whirlpool 22 cf refrig. Total electric and uses less amprage. It depends on how they connect it, as some can run on batteries for several days or you need to install a true sinewave inverter (not the modified sinewave that usually come with a coach). Use rubber mats on the shelves, and some baskets to hold small things. To keep the door closed, use velcro...We travel the USA and had no problems. What part of the country are you in? BTW, love the ice and water in the door. God Bless you with safe travels
