Every RV generator conversation is secretly about one appliance: the rooftop air conditioner. A 13,500 BTU unit runs on modest power but demands a serious surge to start its compressor — get the sizing right and everything else in the rig is easy.
Running watts
1,300–1,700W (13,500 BTU) / 1,700–2,000W (15,000 BTU)
Starting surge
2,800–3,500W (compressor start; more for 15K units)

The default RV answer: starts and runs a 13,500 BTU AC with capacity left over, TT-30R built in, remote start from inside the rig, and 52 dBA won't get you glared out of the campground.

Generally yes — 13,500 BTU units surge to roughly 2,800–3,200W and run at 1,300–1,700W. A quality 3,500–4,500W inverter handles it; add a soft-start kit for comfortable margin or for 15,000 BTU units.
Yes. Paired 2,200-class inverters deliver ~3,600–4,400W combined, enough for a 13,500 BTU AC — that's exactly why parallel kits exist.
