I looked at linking two 7000's, its still on the table as we could still pivot to a gas truck instead. Like another person posted, we wanted to go with a kubota lowboy or the cummins 1800rpm 10kw commercial gen and then connect to directly to our diesel fuel line in the truck, just creating a single source to fill and allowing a larger run time capacity on the generator as well. In terms of noise, both diesels seem to have fairly low dB outputs (mid 60s compared to mid 50s with honda, however claims that db output when on eco mode, they are quite brain rattling still at a full load). Additionally, being liquid cooled, i am assuming we should have an easier time creating a sound-proof enclosure without the concern of overheating
