Josh, I grabbed the Isotherm 3701 at Defender's annual sale. Added costs were ~15-18 feet of 10/2 AWG duplex safety wire, a new 15 amp breaker, miscellaneous connectors, fasteners, etc. probably pushed the cost to $1450-1500 total.
I also added a new dedicated start battery and combined my 2 Group 29 batteries into a house bank. That probably added another $175 for the battery and cables. The 3701 specs call for 0.65 ah avg and 6 amps max for a reasonably insulated box up to 7 cu ft. Off line discussion with Fred Street indicated that 3 ah average max be more realistic (75 amps/day). The combined bank has a reserve of 420 minutes (at 25 amps). That equates to about 175 ah or about 2.5 days of refrigeration run time. I cut a window into a bulkhead on the inboard side of the ice box and found 1 1/8 inch of sheet insulation. I suspect C&C glued same around the 4 sides of the box. No idea if the bottom is insulated. I had added 3-4 inches of pour foam to the outboard side years ago. I think Touche' box is around 6-6.5 cu ft and a bit short of reasonably insulated. I don't have any battery monitoring capability so I'll just have to learn through use what the battery draw is.
