this. any dwelling you reside in be it for 30 years or 30 min. if deadly force is justified during a break in you are covered. The SCOTUS ruled in favor of a camper that was busted for possession while camping. The rangers entered his tent and found drug "items" . case went to SCOTUS. they ruled in defendants favor as the tent while not a permemant fixture was a "dwelling" and warrant was needed to enter as a "reasonable amount of privacy was expected as it (at the time) was their living quarters. Same goes for your vehicle, covered while transporting a firearm (in a safe:) manner) in states that do no trecognize CO's CCW reciprocity.
A babysitter while not "resident" is in the dwelling and does have a right to self defense. If again DF is needed they stop the threat you would be hard pressed to find a DA that would bring the shooting to trial.
YMMV. This is why everyone on this and any other gun board should have a reliable, knowledgeable firearms smart attorney as a friend or a phone number to call if needed.
no one here (unless admits it) is an attorney. asking on this board what your legal rights are is hearsay.
