How best to improve a primitive RV site to rent it out?

Does the cell service work well enough to use a phone as a hot spot?

Probably not. I have occasionally been able to make a weak phone call or get a very weak data connection from Sites 1 and 4, but it seems to depend on the day and maybe the carrier. No service at all on sites 2 and 3.

Thanks for your input!
