See you at the Ralley!

Roger. Thanks.

JD: SOME mfg, like Battle Born, specifically warn not to keep their batteries on charger at 100% for long durations. You may want to verify what your MFG says. GJ

And I "ASSUME" that you have run a #4 AWG all copper cable from the frame to the B- terminal as well. I have to adopt a different set of charging parameters, and once done will check performance. If it does not improve, then I will likely try adding such cables to the anderson connection at the TV rear bumper and battery. Would certainly prove your hypothsis. BTW: Assume is often spelled Ass of You and ME. LOL

Crazy Horse said use gasoline. But I think rocket fuel would be more effective. GJ

Ty J: Is this a drain tube? If so it would be simple to penetrate the hull on both sides and pipe them down via the existing Dometic drain tube. GJ

Art is bringing my hydraulic crimper too the Rally. If you have the measurements (with a bit of slack of course), the right cables and lugs to fit THAT cable, I would be glad to mechanically crimp them for you. This cable size and lug ID issue has stumped some of the best of us, so I highly recommend buying them from the same vendor. GJ

Wow you are of of the VERY few that are actually seeing 30 amps from the 30 amp model. I hope you will be at the rally so I can your setup. Good job. GJ

You are correct in that OTT video says two gallons as well. I use 2.5+ gallons. Just a matter of how long your stroke is! 🙂 GJ

Flooded Lead Acid (FLA) starter batteries usually employ maintenance-free designs. But FLA deep cycle batteries require regular maintenance to each of their cells. The plug you are showing typically serves as a vent path. They are not intended for service, but on many battery's they can be removed for adding DI as you suggested. The question is does this vent provide a pathway that DI will flow equally to all the individual cells? Regardless, doing so can be very dangerous. A small droplet of sulfuric acid splashed out of the battery can easily blind and/or disfigure. Personally IF it were mine, I would not even consider trying to refill these batteries. Just not worth the risk. Especially since they are 5 years old. Bad news you need new batteries. Good news is you need new batteries, and it is a perfect time to upgrade to Lithium. See JD's and several other posts on DIY battery upgrades. Good luck, GJ

Scott Oliver's design is amazingly effective in giving us a very safe towing trailer. Heavy, compact, non-swaying, a shape that reduces side loading of gusts, tandem axle, four shocks, EZ flex, the strongest frame of any trailer in this weight class, E-rated tires, and the Anderson Hitch transferring weight forward for those that need it and an extra long tongue. The amazing part is the design. Even more amazing is that it is Stock on all our trailers. GJ

++++++++++++++++++++++++++++++++++++++++++ Actually IF I were Dometic, with all the really bad publicity they sadly have received about A/C units that owners have despised so much.... I would wait about 5 years before introducing a new one in the USA. After that we all will have totally forgotten about our mutual bad experience and they will come out with an inverter unit with internal drainage, a fan selector switch tied to the AC Compressor run, and a remote T-stat/thermistor. In a lower profile unit using a brand new even more efficient refrigerant and sold at half the price of their competitors. GJ

Another approach is to remove the old wash cloth bar assembly entirely. Here is a teaser about it. There is a full DIY that Art wrote up I beleive. DIY - Art's Bathroom Cabinet Magical Transformation.docx

Diane: Thank you for posting back. Frankly the cost is super reasonable.

Dear Santa: I've been a good boy, can I get one of these? GJ

Thank you Geoff. I will be adding three likely so it would not work well if they are not matching to the OEM. I do appreciate your suggestion. I do agree that the OEM ones are not the best for their intended purpose though. If the OEM ones are no longer available, I may just bite the bullet and replace them all to match. $$$ though.... GJ

Searching the forum for the source of our thru the wall coat hooks. Saw where an owner posted this before, but not finding it now. Thanks GJ

PLEASE correct me if I missed the spec: Both units will need a Mod for the fan running all the time when on (No fan off with compressor switch), for remoting the thermistor to a central of cabin location, and don't have a gravity drain feature like the ole hammer mill Dometic. I really hope that they didn't go down the same "rabbit hole" that Houghton did. GJ

I really like the fact that these units have Inverter design compressors. For me, the Houghton's two Mods issue and not having the Inverter compressor edge: For sure would take the Houghton off my recommended list for sure. The 45 Db on low speed may be correct. If so that's 2X WOW!

Yep. Sold mine for $550.

Most likely. If you want to get an idea about what is required for the Houghton's, it very likely would be similar for the Atmos units as well. The Mod to turn supply air fan on/off with the compressor is just a ACR style relay. I had proposed this long ago and one of the SOB owners ran with it. GSM Bear was very helpful in the process. The Mod to remote the thermistor that controls when the compressor comes on / off is just an extension of the cable of the existing thermistor or just buying one with a longer tail. Normally an easy mod if your trailer has an easy path to where you want to be sensing cabin temp. In the case of OTT's, it was a tough nut to crack. There is EXTENSIVE "Deep Rabbit Hole" posts on those two topics. Some of my thoughts and a lot of others are attached below. Warning: it gets deep into it in the attachments. But in actuality it is not impossible for a talented and courageous electrical tech to accomplish these mods. But as you said, "Such mod would void the warranty so one is for sure at risk. Last thought is that if a person were so inclined to do the mods, I would run the unit for a full season just to make sure it is good to go, then decide to proceed "at risk".

Spot on! Those of us who have completed Mod 1 and Mod 2 for the Houghton's really like them. But having to do the mods to get there is not realistic for most of the audience with Mrs. Lincoln. Same darn mistake Houghton made. Where was the ATMOS designed an where manufactured? The Dometic Penguin II also had bi-lateral drainage. But it was an internal drain down a tube to near the port side tire. The Houghton and if I am reading your note correctly both flow the condensate over the roof. Please confirm. IF so, then both of these units are not quite as good in the condensate drain design as the Ole Dometic. All over-the-side drainage designs have to be bi-lateral. Reason is that with Heat Pump's you may well be operating the system in freezing temp's. If they were not bi-lateral designs for flow, you would have a condensate pond inside the roof top unit on the low side. Such ponds in freezing weather can cause serious problems. I wonder how long it will be before we have Houghton type Mod 1 and Mod 2 for the Atmos units?

Nice work JD! Perfect loss of 4 holes and creative cable stabilization assembly (AKA Bolt). A+

Good, but long, video. Thanks for sharing. It appears that the Atmos 4.4 design is very well done. Has many of the same concepts used by the Houghton. Two design details for further update by Atmos owners: In the video they did not make it clear that when the heat pump is in cooling mode, that the fan does not have to run when the compressor is off. This is a deal killer if the Supply Air Fan and the Compressor cycle together. Unless you are one of the 10%ers as discussed already. The other detail that potential purchasers should be aware of is the unit's height. Here is a comparison: Dometic Penguin II 9 1/2" Houghton 9" Amos 11.14" For most not a problem. For some that 2.5" could be if you have a 10' entrance height. Just measure and be sure especially if your entrance to the storage factify has an UP ramp as you back in. Looking forward to learning about the cycling of fan and compressor topic. GJ

Not me. Past was 3 - 4+ month full time and rest in HI. This year two trips scheduled for a bit longer. GJ
