Yes, you can use it. I've never yet seen a 240v hot tub circuit that didn't have a neutral.
That is not correct. There are several hot tubs that are strictly 240V including mine, that don't have a neutral. The pumps, lights, blowers, etc. are all 240V. No need for a neutral to create 120v(just like your home air conditioner).
To the original poster, I would have an electrician see just what your old hot tub had for service. Even if it was a 3 wire 240v he could use the existing wires to create a 120v-30amp rv setup with a hot neutral and ground.
