Stacey,
Nice idea, have read of several doing something like that. Also, just parking with the fridge side away from afternoon sun can be a big help, and if in the same place for a long time, a shade of some sort will also help.
We also have a wireless monitor that shows temps in the freezer and the fridge areas to let us know if we need to move the settings higher.
These 'movable homes' need a lot of help to overcome bad engineering and bad construction, no matter how much money you spend. I look at the new DRVs and then read about the issues, and just stay with my aging unit.
If I don't spend at least $500/year on fixing things, it's because I've gotten lazy.
