Lloyd,
Honestly i only have about 400 lbs of my own stuff. I'm not too worried about the weight. Most are around 100 to 135 pounds. And my front compartment under the rv has been reinforced for the previous owner who had a generator in the spot. I'm only interested in one for boondocking and power outages during the winter. I'm planning to get a Dual Fuel version to use my on board propane. Honestly I have found several different versions that are very quiet too around 65db.
