Welcome to the club Nick!
As the owner of your initial inspiration, you did a fabulous job.
Not sure if you noticed but I came back 3 yrs after my original post and showed how I measured the tongue weight both empty and loaded using a
bathroom scale ...
I'm getting started on a new project to mount a 3kw (3750W peak) generator with an 8.5gal tank and a silencer box (somewhere) on the pup to run my AC unit. Needless to say balance is becoming critical since my dry tongue weight is 260lbs and my loaded (2 quad) weight is 675lbs.
This will be in conjunction with switching to either two or four 6V golf cart batteries and solar panels for trickle charging on longer trips. With my previous two 12v deep cell battery setup, they'd be dead in 3-4 days where I'm planning a 7 day trip this summer with no hookups
Anyhow, good luck and enjoy the great outdoors with your toys and (nearly) all the conveniences of home
Later,
WET
