I did it on my 16' Scamp
. It was originally equipped with just an icebox, and when I did all of my mods, I installed a small "dorm" fridge in the bottom half of the closet by the door. It is white, about three feet tall, 2 to 4 cubic feet (I can't remember). It works wonderfully; two years in and never an issue. The vibration and jolts have had no effect on the mechanical systems of the fridge.
Its small compressor unit puts out very little heat. Even so, I installed a small vent between the closet wall and the under-sink area for circulation. I have twin deep-cycle gel cell batteries on the trailer tongue to power all of my systems, and it all works fine. I run a Tripp Lite 1000 watt RMS Powerverter. It keeps the batteries topped off when plugged in, auto switches to battery
power when unplugged, and controls everything without me having to think about it.
The seven wire trailer plug has the twelve volt feed hooked up to keep the trailer batteries charged during travel. The feed from the truck is through a relay and is only on when the ignition is on, so the truck battery
doesn't discharge when parked in transit. I camped without hookups once, and the batteries held their charge overnight just fine. I simply started my truck in the morning and allowed the truck's alternator to recharge the trailer batteries.
is bolted down tight, and has never shifted. I did have to fabricate a door latch that would not fail during bumpy travel! That was it. I would enthusiastically recommend this mod if you have a good battery
and inverter, as well as a 12v feed from your tow vehicle to keep the trailer battery charged while in transit. BTW, the refrigerator
gets ice cold. I have the temp dial set on a "medium" setting. The only thing that doesn't work great is the little freezer. It's one of those where the freezer section is simply a small metal divider with the coolant passages around it, not a totally different door. It does not keep items hard-frozen.
I completely prefer this setup to a standard RV 3-way fridge. It's nice not having to worry about pilot lights
at filling stations! Plus, I know I can replace this unit any time if required for just over $100.00
