Camping World is going to be hard to beat for pricing on a new one.  Take them the model and serial number from your dead one and they'll fix you up.

Be careful with any used fridge you find, both Dometic and Norcold had several recalls on their units.  You should be able to search the model number for anything you find and get more information or just call the manufacturer.

Good luck.

What's wrong with it?.

If it just won't get cold it is probably wax bound.

If you pull it out, turn it upside down for a day, preferably in the sun, flip it right for a day, one more day upside down, put it back in and fire it off. Betting a"cold one" it will work perfect..

This is a very common problem if it had not been used for a while.

It is the older one but the one im gonna look at is newer with computer board its 59in tall by36 wide and 24 deep with a ice maker think its worth 1000? They have it posted for 1500 claim to paid 3400 idk much bout refrigeration
