Great company..Great communication..Fast shipping. A+++++++++++++++.<br>Will do business again.

Very detailed list of part fitment. Radiator fits and functions very well. BUT, and this may be no fault of Autoplicity, I received the radiator w/holes punched in the box and some of the cooling fins bent. It wasn't bad enough to warrant a return, thoug

Satisfied

My ARB 50qt fridge/freezer arrived quickly and it was way cheaper than anywhere else. I was a little leery only because of that. However, I received the fridge and saved about $65 over even Amazon. No problems.

Pricing was good and customer service quick to respond.
