The HTT is still in winter storage. I'll report back in a new thread once I complete the task.

I have had two trailers. One a 1989 Kit Companion and my new one, a 2015 Jayco 27RLS.
The parasitic load on both of them was about .3 to .5 amps. That is with everything turned off, or as "off" as a modern component can be, without removing a fuse or unplugging it.

I used to think you would get two weeks. Guess not.

Never really did the math before but it makes sense. If you had a 1 amp parasitic draw that is 24Ah per day. Two days boondocking without using any additional power and your low voltage alarms (CO & propane) will start beeping if you are on a regular group 24 battery.
Even 4.5 days on a pair of 6 volts and you will be down to 50% charge.

To me 12 Ah doesn't seem like much, but when you put it in context, you are right. The trailer will kill the stock battery in 4 days without anything else.

Now you have me curious to chase down what the 0.5 Amp idle draw comes from and how much from each thing. Curious if a majority is the CO and Propane or if it is just the electronic gremlins in the electrical system munching away.

I did a power audit on our 2010 28BHS, here is the results.

Water Pump 5.0 amp
Furnace 6.0 amp
921 bulb 1.3 amp
Stereo on 0.4 amp
Exhaust fan stove 1.4 amp
Exhaust fan bath 1.25 amp
Signal booster 0.1 amp
Monitor panel 0.25 amp
Water heater burn 0.6 amp
Water heater @ temp 0.02 amp
Parasitic draw 0.35 amp (radio, CO detector)
Refrigerator At rest auto 0.34 amp
At rest gas 0.34 amp
Auto cooling 0.58 amps
Gas cooling 0.71 amps
Furnace run time @ 10 C (50 F) 10.66 minutes/hour
Furnace run time @ 5 C (40 F) 17.28 minutes/hour
Furnace run time @-5 C (22 F) 32 minutes/hour
Sue's computer AC draw Charged = .16 A = 19.2 W Charging = .34 A = 40 W
My computer AC draw Charged = .10 A = 12 W Charging = .29 A = 34.8 W
