Looking for a propane powered crock pot.

We have a Lance 1685 travel trailer and a sailboat ... and I would enjoy a slow cooker in both ... but don't want to leave electricity running while we're gone. Here's some information from my sailing blog that features a low fat slow cooker lasagna recipe as well as alternatives to an electric crock pot. We're still vascillating on which slow cooker to buy, but after hiking 16 miles in Glacier last summer, all I wanted was dinner ... not to have to COOK dinner!

Dinner Cooks Itself, Thermal Cookers

I just need to make a decision and BUY one!
