Also...I read on another post that people have replace interrior lights with LED, anyone done that in the X17Z? I might do that to help battery life.
From topics on this forum, your 12 volt battery capacity will limit you; not propane.
Changing to LED bulbs will help, but your TT furnace fan will drain a battery quickly. Buying a portable propane heater is what some folks have done to have heat without draining the TT battery.
After that, how long your battery will last depends on the individual and their needs for electricity for lighting, entertainment, etc. Use 'very little' power and the battery may last 4 days, use 'a lot' of power for lighting, games, entertainment, etc. and it won't last that long. But what is 'very little' and 'a lot' etc. is very subjective.
After the above generalization, it can become more 'scientific' by calculating battery capacity (amp hours) against how many amps each item draws and how long each item is on. Some of the folks on this site may be able to help you with that, if that is what you're looking for.
