Due to the weight, I'd rather have two 2200i generators. You can hook them together when you need the extra power but, if you aren't going to need the A/C, you can leave one at home. The 2200i weighs 45.6 lbs while the 3000i weighs in at 144 lbs. Lifting 45.6 lbs twice is much easier than lifting 144 lbs once. Price-wise, the 2200i is advertised at $2,019 while the 2200i is advertised at $1,009 x 2 = $2,018, plus you're getting more wattage. Here's some info on paralleling two Honda generators:
