I do not think that I would attempt to parallel it with anything but another Sportsman 2200. i do have a Sportsman 2200 gas only version and have set up and watched used the dual fuel on propane. I also have a Sportsman 800.
All three are good generators. The dual fuel version on propane ran a 5000 BTU A/C for 40 hours, stopped long enough to have a full 20 pound tank put on, the oil checked and then run until that tank was empty. I watched it run like that for a few weeks in the 112 degree heat of Quartzsite. We changed the oil every other tank and would have every tank with a 30 pounder.
I picked up my 800 nearly three years ago and have no complaints with it either.
