yes, try connecting the generator to a metal water pipe, provided it is really a decent earth ground, it will satisfy the EMS test for ground/neutral bonding. And it's probably the safest setup. Now the generator and trailer are truly connected to an earth ground. If the EMS still shows "open ground" it means the water pipe is not a good enough earth ground.
Or just build the bonding plug I described in an earlier post.
I would advise that you do NOT ground the generator to your truck. First, it won't provide a ground path back to the panel, hence the EMS will still see an unbonded ground/neutral, and second, it is a potential safety hazard, A fault between hot and ground now potentially has your truck live, since the truck is likely not well grounded, being insulated from earth ground by the rubber tires.
