New Fiver - slides and jacks use - w/o killing battery

Brought my new fifth wheel home yesterday - don't have shore power at storage lot, so I'm curious how much I should be able to operate the slides and electric jacks off of battery power... don't want to kill the battery to the point that I can't raise the front jacks back to the point of hitching back to the truck, but want to be able to run the slides out to show the camper to friends and need to run the jacks a few times to get familiar with them.... should this be a problem?

Also curious about residential fridge - with the old TT, I'd go fire up the fridge the day before I planned on loading the camper (turn on fridge Thursday afternoon for Friday departure, etc) - how far ahead should I turn on the electric only residential model?
