Well I appreciate the helpful responses.
We bought the Whitehawk and love it. We have more than enough storage space for what we actually use and we felt extremely comfortable towing it with the equalizer hitch we bought. We actually have spoken with many people who fulltime with the exact same vehicle, same # of children (or more) and are towing a heavier weight! Our vehicle is a beast if you haven't seen one in person. We do have the artic package on our RV and will skirt/winterize if needed. As for the deep freezer, we are considering taking out the mini fridge outside and seeing if we could fit one out there if even possible. We will likely switch out for a residential 10.7 cubic foot fridge that will fit perfectly in place of the 8 cubic foot one we have in the RV, that will help even if we can't get a deep freezer.
