Dometic RM182B

Greetings,

I gonna post this one in English as my German is too poor...Sorry.

Got a Dometic RM182B in my Wanagon, and think it is time to replace it with something else more effective.

Has anyone every tried to replace the Dometic RM182B, and what was the outcome? Working, or better not?

Any one got the exact sizes (height, length etc) on the fridge? And also pictures of a proper replacement?

Thanks and regards, K
