I'm wondering if there's any difference between the ARB and Engel Transit Bags. I have an older Norcold 34 qt. Fridge/Freezer and want to get a bag for insulation purposes. Cruiser outfitters has both the ARB and Engel bags, but the price is different, ARB is more.

So does the ARB insulate better or are they basically the same?

Also, is there any room inside the bags once they are on the units? Could one slide some sheathing insulation inside the bags on the fridge to add to the insulation?

Thanks,
Ben
