trailers are really complicated to insure with permanently installed equipment. my insurance agent has trouble understanding what needs to be on there. john, the easier way would be to have it insured on your end as a rental and add that in to the price. I could add something like that to my insurance but it would be a PIA. the other thing is alot of guys suck at towing a trailer. I would like to add a second trailer with a truckmount in it. the only thing is I don't trust my help to not crash the thing into something. carports are hard on trailers, so are curbs and the metal pipe things that protect the gas pumps.
from a rental standpoint and insurance, maybe putting the unit in a van might make more sense, because automatically it should be covered for any driver on your own insurance as well as the insurance of the guy driving the thing, plus an idiot is less likely to crash it or ding into something.
