The best hand Electric Trailer Dolly for the money & why?

My Step son owns a 10K Trailer Valet Dolly & he is going to let me borrow it & I have plenty of access to trailers being I work in the film biz as a Teamster & we all have trailers & trucks & etc.

So I'm sure access to a trailer is not a problem.

I'm going to borrow my sons Trailer Valet & take it to move a few trailers & see what I think?

NO I WILL NOT PAY TO STORE IT!

I've backed hooked up to my Bronco, a boat & a open car trailer into my back yard.
So if worse comes to worse I'll just go with a smaller Trailer.
