Dometic knows their sn rated fridges cannot perform well when the temps are above 85F. They've made several business decisions to not sell a t rated or even st rated fridge in North America -- at least not anything like the 8 series. Have no idea why. Norcold is basically doing the same thing. Anyone want to corner the rv fridge market? Just start producing a t rated fridge line in the north American market -- one that performs well up to 104F. They do make them. They just dont sell them here.

One. I wanted a smooth flow of convection air to remove heat from the condenser. Given the convoluted area around the condenser is likely to create turbulence and an inefficient flow of air I added some fins to "straighten" the flow and make it more efficient. I was't looking to create hurricane alley but I did want a more efficient convection current.

Secondly, it made no sense to me that the heat from the flame is dumped out right by the condenser, an area you want to remove heat from, not add heat to.

So the channel on the left creates a flue that is isolated from the condenser. Ironically Dometic does make a flue extension that directly dumps the heat to the exterior. Efforts to obtain on in North America weren't successful so I went with the isolated flue instead.

Thanks Ron for info . You are right I found that extension pipe (tomorrow will put it on thread ) in Australia , not here . I don't know about this metal on back of my frig , but Reace
was adamant I put it back , so I did . I think I can get it off if I need to without pulling frig . Do you have figures for your outside temps on your trip ? Very interested what you were dealing with . Pat

Thank you for voicing our frustration . Most people keep quiet and do not want to make waves . We are just at a point trying to help this situation on our own with orthers valuable help. I would just say we are dealing at this point . It's hard to look at a brand new frig that doesn't work . Pat

Wow, nice work Ron. Were you a Tin Knocker in a previous life?

Pat,

That is one of the nicest insulation jobs I've ever seen! A couple questions, I see you didn't do the full length baffle was that per Reace? The metal piece I assume was installed by ETI during build and I assume it takes the place of the baffle?
I sure hope you get good results and thanks for taking the time to document your work

All this talk about prior Domestics operating better than current models leads me to believe the real culprit is global warming...........?

I think it is worth noting that both manufractures make models that work very well. The problem is finding one that will both work well and fit thru the 22" door.

True, but it still begs the question as to why Dometic and other manufacturers offer a tropical performance rated fridge in markets like Australia and Asia, but refuse to do so in North America. The RM8555 and the RM8551 both have tropical rated 'versions', with similar exterior dimensions to our SN rated fridges.

The Australia folks did finally respond but it was about a month later. By that time I'd already done my mod. It still would have been my first choice.

I didn't have any temperatures over the mid 80's but it was warm enough for me. As I mentioned, we had frozen food for 42 days and never had to change the setting of 3 bars. So it did the job for me. Don't know what it would do in 100 degree situations. Don't want to find out.

No, but over the years I've gradually gone from having an all woodwork shop at home to also having a full metal shop. I like building things. By the time I'd finished this car I'd also become quite comfortable working with aluminum.
