I would run the Honda all day, I have my two running right now and they have been going all day and the one has been going since yesterday morning. Wife is doing laundry today so i fire up the second one for additional power. This is your easiest way to do things and you already have the Honda anyways. Still install the pads and set them for ac voltage, they probably only draw a couple of amps if that while on ac setting.

Your Honda will run close to 20 hours at idle or under 1000 watts of supplied power. When the Honda is supplying full power, your tank will run dry in around 7 hours.

Add up what all your pads consume on 120 vac and that will give you a idea of how much of a load will be on the genny.

If you have 4 or 6 deep cycles, Iota converter chargers are the ones that I use. Your onboard converter charger is very likely too small to recharge that many batteries, your looking at a 8 hour charge rate minimum, depending on how much you draw the batteries down.

Likely your unit only cames with one battery, so winter camping and running the furnace and a few lights will kill that fast, even if you start off with a fully charged battery. You could get by with firing up the genny early in the morning to recharge the battery and get the heat going again. But a pain in the butt. Being a new trailer i would have them delete the battery and at least invest in two 6 volt batteries, either Crown or Trojan.

Temporary skirt is going to help with your tanks not freezing, adding a Mr Buddy heater along with the skirt will help alot. More gear to carry and setup though.

I had the Agm batteries, orbital type, big bucks and sitting on my shop floor useless. Replaced with Crown two and half years ago and they work really well. Remember I am in the cold Ontario Canada, and cannot afford a breakdown, off the grid for power and water.
As for enclosing the underbelly, some sort of sheeting will be needed, I don't recall what it is called, then regular pink insulation, stuff everywhere. Your valves and drain pipe will likely be exposed depending on your setup, but heat pads or trace lines will work there.

I guess either way your spending money on fuel for the genny or propane for the furnace and aux heater. If it were my deal, I would gear up for running it all off the genny, change the oil, fill er up and enjoy camping.

I should ask, is this a regular pull trailer or fifth wheel, how long, any slides?????

seconday problem is having your tow vehicle supply 60 amps or so to your trailer while towing. Thats a big draw on your alternator which is likely around that output anyhow, even though with the typical size of wire going to the trailer, and the voltage drop, you would never get 60 amps back there.

Good point, totally over looked that [doh]

Unless he has a PSD like Trailblazer with dual reactors :shock: I beleieve he has like 210AMPS available on his Ford [thumbs_up]

Anyway, yeah, tough to get that back there.

I agree, I would leave the genny running all day while gone, especially since the genny is secured to the trailer. On 12v these heat pads pull 9amps, however while on 120v they only pull .94amps. The genny wouldn't even notice it and run on econo mode for the entire day.

I wonder if the heating strips around the valve area and pipe would not be enough - rational... warm liquid will rise to the top thereby creating some circulation within the tank .... might that be suitable for the day time? Also, would a large styrofoam block or sheet suitably cut and put over the exposed area help? I have never had this problem, so I am just guessing or maybe day dreaming or whatever...

Actually you could also run the genny in the truck on the way to and from camp to keep the tanks warm. Think GoinKZ and myself discussed this option last winter prior to our bunking in at Mac. A small Honda/Yamaha 1000W or bigger could easily manage the pads and the furnace.

Yep totaly viablr option. A lot of the reason I added 2 xGR27 was to hopefully avoid thst issue. :) But yes, genny is an option. Being a TH is not genny prepped?

Gensets are usually optional equipment.

I believe the OP posted that he was running a 3K watt Honda. Could easily run that in the back of the truck to and from. I'd think it would just idle away under eco throttle powering those, the furnace and the converter.
