Unfortunately, it will not work on our earlier generation compressor control board, so we are either out of luck or have to spend a lot on a new control board, it appears.


If we were getting a current generation, we certainly would get the latest version, as it look like a good design.


One of our criteria in looking at the controllers was to make sure that a manual thermostat could be wired in parallel but not connected, or turned off at a switch, so a failed controller wouldn't ruin a trip for us. And I am pretty sure the newest versions would be able to be setup that way.

Roadtrek's installation is lousy. But add some computer fans to blow air over the coils and the Dometic will run great even in the southwest in summer. You have to close off the two lower vents in the upper vent panel so the air blows over the finned condenser tube. I did this to our 2001 200V about 15 years ago.

The fans reduce the duty cycle, saving power. I refitted our van with a 200 ah battery. I don't worry about leaving the fridge running on the battery for a couple of hours.

The propane burner takes a few long seconds to light. It should be quite reliable.

We don't fuss much with getting the van super level. We boondock quite a lot.

I replaced a Dometic RM8505 with a CRX110; if I looked at the dimensions correct ly the CRX110 is fractions of an inch smaller than a RM2333; Might be an option.

I only have 1 house battery in my 1995 dodge class B. How would the new fridge work while boon docking?

I installed mine this past January.

Best I've been able to determine mine uses between 40 and 60 ahrs per day (24hrs); I keep it on the coldest setting most of the time and it can be pretty hot in NC; prior to replacing the refrigerator I averaged 50 to 70ahrs per day, now I'm 80 to 130;

I normally keep the gas off thats worth about 14ahrs per day; the 130ahr days were this past October at Pisgah Campground on the Blue Ridge Parkway (elevation around 5,700 ft); it was just above freezing at night so the gas was on and the furnace ran quiet a bit.

Most of the time that the refrigerator is running it draws 3.4 amps.

At Pisgah I ran my generator an 1 hr and half each day to charge the batteries; was there 3 nights.

So one house battery would be pretty difficult unless you find one a lot more efficient than my CRX110 Dometic.

I got a 2015 190P in september in houston and travelled with it in texas Georgia and back home to Florida. I thought about immediately replacing the dometic fridge, but i decided to wait, and i'm glad i did... I know people have had lots of problems with these units, but mine is working very well... When i am leaving on a trip, i put 2 blue ice containers in the lower 2 shelves of the fridge, set it to DC and by the time i arrive at my destination, the freezer has frozen the ice cubes in the tray and everything is very cold in the fridge. Of course, i switch to propane as soon as i get there.

the thing i like most, is the improved ability to boondock. the fridge uses very little electricity on propane, leaving me the amp hours to run other things such as the computers, tablets and other electrical accoutrements i travel with... In the moring, the batteries have usually gone down to 3/4 or 2/3's and the solar has them back up to 100% by early or mid morning.

I have had TT's in the past with problematic dometics, so i understand the other side of the equation also..

Nice to hear good news on a propane fridge. I'd guess it's because Roadtrek did the installation right (providing good ventilation).

The problem with my dometic unit is the flame blows out when I'm on the road. I tried putting a plate in front of it but that didn't work either. How can I turn up the pressure to increase the flame because I do run it at maximum setting and it still goes out.

I love my Rialta however hated the efficiency of my Fridge.

It took 8 hours to cool down on AC Power plugged in and would drain a battery before you knew it.

Didn't want to bother with the propane feature or routine cleaning required of burner.

Researching I found out there was not a new fridge available to fit the area.

I have a high quality portable fridge for my work van that I've used for years.

It uses a Danfoss BD35 compressor for cooling. It's quite efficient.

Never has caused a problem plugged into my start battery even on 95 degree days.

I found a cooling unit easy to modify my existing Rialta fridge using the same technology.

Adler/Barbour CS-NC-15 Super Compact cooling kit . Normal Refrigeration Capacity: 8.8 cubic feet

Easy to install. Just cut a 8 X 12 rectangle in back of old fridge and fasten with 6 screws. You're done.

The cooling unit is inside of fridge ( about 2 inches deep ) and compressor is outside ( back of fridge).

I cut off all the pipes and old cooling apparatus. The new unit uses the old switches and fuse.

Within 30 minutes it cools down to fridge temps. Within a couple hours it gets to freezing.

$700 for unit You'll find it online.
