I don't think there's any argument going on here nor did anyone ask which is better. The OP asked for suggestions and experiences. Why does it seem like discussions here frequently end up with a need to determine a victor?
Very well said and I agree with your analysis of posts here. It wasn't a question of comparison of which way was a better direction to go (for me), rather did anyone have any experience with the Isotherm brand.
Well I got my answer on a few boat forums as Isotherm is mainly marketed to the boating community. They seem to have a fine reputation and, for the most part, people like them. My experience in the buying process has been fantastic, I hope installation and user experience is the same.
The reason I chose Isotherm (rather than other Danfoss compressor models) is that their "drop in replacement" model for my Norcold 2.7 cu. ft. refrigerator is the Isotherm Cruise 130. The Cruise 130 is exactly the same outside dimensions as the Norcold 2.7 cu. ft but gives me 4.6 cu. ft of refrigerator/freezer space. 70% more interior space in the same package size - that was a definite selling point for us. The freezer portion is a bit small (6 liters) but we're OK with that. I spent an extra $115 on the Isotherm Power Saver electronics (my opinion is that it should include this in the base package) which uses a bit more sophisticated computer algorithm to run the compressor more efficiently. Isotherm advertises up to 35% less power usage but forum folks swear it's 50% less. Some folks claim to have measured the draw with the module and claim about 2.5A draw at approximately 50% duty cycle while cruising in hot-humid areas. That would equate to about 30 amps over a 24 hour period. I'd be very happy with that. We'll see after installation.
My Isotherm unit is supposed to be delivered at the end of next week and I don't anticipate more than a couple hours for installation. For the record I paid $955 for the Isotherm Cruise 130 and $115 for the additional power module. Shipping from MA to CA was $100 but no tax for the online purchase. I'll photo-document the installation and my experience and repost here when complete. I'll also measure the draw and we'll see how the efficiency claims hold.
Thanks for all of the comments.
