Our insurance provides for a rental car if you do not have a frog. I would take valuables, clothes, dump the food or give it away, and you have to trust the repair facility.
Before leaving meet with your insurance company and the shop to have clear understanding of what is being repaired and how. For example are they going to replace the front cap or repair it. As best you can get a firm repair schedule.
If you do not like this option ask how much to make road worthy so you can at least drive it back home. Make sure you get a ft. end alignment. That is what we did and went from SC to NM
This what ours looked like
