Generator sizing issues?
I have a 2017 Jayco 273 Toy Hauler (30 amp) with a single 13,500 BTU AC (according to their website). It has gas/electric water heater and fridge, micro, 2 (TV's), digital antenna, stereo and LED lig...

Should I go to the 4250/3500 or just go up to the 6500/5500?
3500 watts = 29.166 amps
4250 watts = 35.4166 amps
5500 wars = 45.833 amps
6500 watts = 54.166 amps
Electrical math using 120 volts. Watts divided by volts equals amps.
The larger number in the specs is very short term for motor starting.
The smaller one would work adequately at capacity, the larger one would easily power your TT 30 amp system and you could run other extension cords from it for other power uses. Me, I'd spend the extra of the larger unit and get a quieter generator with power similar to the smaller unit. Keep the generator as close to your RV as you can stand.
Something I didn't mention in my treatise above ;)
Note that when the voltage drops, the amperage pull goes UP. For example, my AC drew 1446 watts at 120 volts pulls 12.05 amps after 40-45 wire run. Same AC after 195' wire length, 1446 watts, voltage dropped to 100.7, amp pull becomes 14.34.
