12v furnace install in a park model. (120v) need help

I'm not sure where to post this. We have a 1986 Elite park model trailer. The furnace quit at the tail end of last winter. It had to be replaced. We got an excellent deal on a brand new RV furnace...

A 12V furnace needs a lot of current to run the fan. You need one or perhaps two deep cycle RV batteries, around 100 amp hours each ( the ATV battery is probably around 20 amp hours) and a good 45 amp or so charger/converter to keep them charged. You've got around 20% of the DC power capability that you need. Now, temperature and how warm you like it will cause this to vary around a bit, but basically your idea is right, you are just under-sized to make it work.
