Thanks for all of the suggestions! I really like the price of the Champion 3100. It's an extra $200 for the remote start. I'm assuming it's worth it since that's the one you guys recommended. So I think I narrowed down to either the 1x 3100 or 2x 2000. Are there advantages to having 1 vs 2 other than what was mentioned? Here is what I took from reading your posts. 2x 2000 would be individually lighter, can only use 1 if needed, total power would be more than the 3100. 1x 3100 would be heavier, 900 watts less than 2x 2000, has remote start. I am leaning toward the 1x 3100. To me it seems less hassle to have 1 unit and convenient to have the remote start as the 2000 does not have that option. Also, thanks for pointing out the closed frame. I don't want to annoy anyone with noise.
