It sure can Drew! The Onan Generator - QG 7000i Onboard RV Generator item # CM44MR is the same size as the 5500-watt Onan generator. It measures 33-5/8" long x 22-1/8" wide x 16-3/4" tall and weighs 201 lbs.

What kind of RV do you have?

Thanks for the reply. Currently have a 2019 coachmen mirada. 1600 watts of solar that can run everything but the 2 AC. I have soft start for both AC as it would pull too much when starting after I had the solar installed. Installer told me it was because the 5500 onan was a 30 amp system. Would I have the same trouble with the 7000i?

@Drew You're welcome! No you shouldn't have that problem with the 7000i Generator item # CM44MR but it'll depend on what else you're running at the time. With two softstarts installed you'll have plenty of power with just the generator running. The 7000i has two 30 amp circuit breakers over the 5500's one 20 amp and one 30 amp.
