I'm sure Bill will respond, but IMHO:

• if your only objective is to run the fridge without draining the battery, you may be able to accomplish that with the stock wiring on your truck, particularly since it has the tow package.
• given your 5-6 month outing, I would personally rather buy a nice battery and solar array setup instead of spending the money I did on the DC/DC charger. That way, you are likely to make the drain on your battery irrelevant, since a good-sized solar array will make up for it. And not only that, you may find that they sufficiently charge your batteries so that you rarely have to use your generators, which would be a huge plus.

That being said, you can definitely add new wire to your truck and TM to provide a healthy charge to the TM batteries while the fridge is running. Someone on this forum ran some heavy welding cable and was getting a very healthy charge to his (4?) batteries on the TM while running the fridge. And he accomplished that only by adding wire, e.g. no DC/DC charger.
