Uhaul hit me – can I use both my insurance and uhauls?

Awhile back a kid in a uhaul hit my car. I got my insurance involved but was also advised to file a claim with uhaul to see what they’d offer me. My car is in a shop and my insurance has already worked out the details with the shop so they will be proceeding. Uhaul just emailed me letting me know they will send a check.

I’ve never dealt with anything like this. Do I let my insurance handle the repairs and also cash the uhaul check for any additional charges?

Thanks
