XLR Hyper Lite 29HFS wall studs

[selandbe]

I have a 2018 XLR Hyper Lite 29HFS and i would like to mount a couple of tie down points on the wall for securing the gas grill while in transit ... i would like to mount something on the wall directly across from the small back door ... between the wheel well and the track for the bed and couch ... anyone know how to find the studs in that wall? I could really use some help because i have a small trip planned next week and would like to be done by then.

Thanks
