Our 2008 & 2012 Montana fivers had RV reefers and the current 2018.5 has the Samsung residential and we prefer it by far. It depends on how long you travel per day. We travel 6 hours or less and it would be no problem for it to be unplugged that long. In our case I would replace with a residential and it can be done for MUCH less than 3 grand. I would measure my space available very carefully and then take my tape measure shopping.
