We have one also. Works great but cooling slowed down as battery voltage drops when camping.
Solved that by installing a dedicated lithium battery, where voltage remains constant until almost fully discharged. Lithium battery is charged, when driving, from the optional second battery under the driver seat, using a Sterling battery to battery charger.
Our fridge is installed backward (lid opens from back) so we have easier access when camping. We also made an angled small wooden base to keep it more level and steady.
Wow! What a great price!!!
We have the dometic cf25 slim and tall. It also fits between the cargo van front 2 seats. Although, it is a tight fit (with the insulating cover), we love it. It works for us.
