Furnace blower?
Does anyone know how many amps the blower pulls? The reason I ask is we've been awaken by low bat alarm while running on bat with the furnace heating the Lance. We've had the bat checked with a load t...

You are welcome Bill. Most RV batteries are around 100ah at 20 hour drain rate. 2 batteries will double the length of time allowed to stay out without recharging.
I have upgraded my batteries to Interstate 6 volt deep cycle (2 batteries of course) rated at 235ah over a 20 hour drain. This should allow me at least 2 days of winter camping without needing to charge with my genny. Rarely do I stay in one camp spot more than 2 days, so the running of the truck will recharge the batteries.
I chose 6 volt batteries for the specific reason that, with half the number of cells in the same foot print of a 12 volt battery, the plates in the battery are thicker and there fore stronger and will hold up to the rigors of rough roads better. The trade off is, if one battery goes bad, I'm out of the game. Whereas if a dual 12 volt battery system has a bad battery, there is still the reserve of the single battery to handle the job until replacement can take place. Because of that, I installed a switch to jump the truck's 2 batteries to the camper's breaker panel. I can use the truck batteries in a pinch. I installed an automatic disconnect that will shed the camper load if the truck batteries start to get pulled down too far to start the truck. It's called a battery buddy. If voltage drops below a preset level, it trips and isolates the truck battery from the camper breaker panel. I leave it tripped all the time, and will set it if and when I need the emergency power of the truck's batteries.
Yeah I considered 6v but went with dual Gr 27 AGM's which we are very pleased with. More useable amp hrs than wet cells and I have to say I am VERY surpised how quickly they recharge just off the truck (OEM charge wire). We are fully recharged in 2-3 hrs...easily.
The 2 AGM's give us enough juice for a weekend of ski camping...by day #3 we will need to either run the genny or go for a drive...our typical ski weekend is 2 days on the slopes and then head home anyway...so it all works out.
Thanks again for the data.
Bill
