Running fridge while traveling off truck

I'm a little confused too. Why not just run it on propane? I always do. In fact it uses so little propane and because I often plug into places that barely have enough currant I almost never run mine on electric.

You need a three-way fridge ... gas, 110v, and 12v. Then, you run a charging / running line (8g or larger) from your alternator to the fridge.

OR, if it's a two-way, 110v and gas, then you need an inverter (converts DC to AC) to change your 12v charge line to 110v while driving, and run the fridge off the 110v inverter.

You need to know what size fridge motor to know what size inverter you need.

It's simpler if you have a three-way fridge. Run on DC ... but it will only keep it cool while traveling, will not work as well as gas or 110v.

Which ever way you go, make sure you have a cut-out for when you're parked, or the fridge will drain your truck battery. Electrical power on the fridge uses a lot more than gas.

Another option run the gas while you travel - shield the gas flame from the wind so it doesn't blow out. Some will disagree with gas on the road, but we've been running our fridge on gas for years with no issues, as have a lot of others. Make sure you rig it so it's safe, doesn't wind-blow.

I don't have to wait for the fridge to change over and cool down again from changing it off propane.

I don't understand this part, but, why not just run it off propane?

Doesn't the propane setting do that? Mine does.. ;)

This will probably get into the good ol' running on propane ordeal that usually gets pretty heated...

If you must run it on electric while driving, setup a straight inverter setup wired directly to the battery and plug in the 110v plug into it while traveling and hope the trickle of charge the tow vehicle provides takes care of it..

You'll need some pretty heavy gauge cables running from the battery to the inverter. The longer the run, the more voltage loss you will have.

Good luck!
