We’ve used both.....a 6500 Onan and now using 2, 2000 Honda’s for parallel service. A plus for the 6500 Onan, great for running 2 AC’s.....but was a tremendous “propane hog”! At minimum load.....merely charging batteries, it would empty a 40 pound propane bottle in about 11 hours. Then....it’s time to get the tank refilled. Not practical unless you’re camping next to a propane facility!
The little 200’0’s are great, as they are fuel misers’, and can be easily refilled with extra fuel cans brought with you. If you only need to charge batteries, one is plenty.....very quiet and fuel efficient. This also gives you a back-up generator if one fails (not likely). The primary draw-back.....2 generators only gets you one AC. The other inconvenience is, (though not major) getting both out from storage, connecting the “paralleling wiring” for the AC, and securing from theft. For us the ideal set-up would be, a single 2000 if the AC will not be used, and a 3000 Honda placed/cabled (theft) in the back of the truck. This is a very easy convenient way to provide a generator without handling the generators at each change of location. Though, to make it practical, you need to install a 50 amp reception in the front of your 5er. This can often be handy when campground utilities are not “friendly” to a rear receptacle. We had a 3000, and regret selling it. The 2000 would be great for cool weather camping (battery charging) and the 3000 for summer camping! memtb
