How many of us are there? Owners of Dodge based RV's?

I would do the same as Stingray.

And then I'd install a new propane line and a 3-way fridge. I bought mine on Craigslist for not a lot of money and my husband fixed the 12v (wired backwards) so it runs correctly on propane, 12v and 110v.

We run the 12v while driving so we don't have to stop and turn off propane at tunnels, then switch to propane as soon as we reach our destination. We cool it down via 110v before we leave.
