TT plugged in at home?

To repeat, the standard here in N America is 120 vac +/- 5% which is a nominal range of 114 vac to 126 vac. Any previous "standard" such as 110 vac, 115 vac, or 117 vac has long since disappeared in favour of the 120 vac standard across both Canada and the US.

From Mains Electricity ...

"In the United States and Canada, national standards specify that the nominal voltage at the source should be 120 V and allow a range of 114 V to 126 V (RMS) (?5% to +5%). Historically 110 V, 115 V and 117 V have been used at different times and places in North America. Mains power is sometimes spoken of as 110 V; however, 120 V is the nominal voltage."

To suggest that a standard 13,500 BTU roof mount A/C cannot be successfully started and run by a 15 amp breaker protected circuit is simplistic nonsense. As long as the unloaded source voltage is within the nominally stated range, the run to this source isn't excessive, and the cable used is of sufficient gauge a 13.5K A/C is perfectly safe to run provided one ensures that all other loads on that circuit are off. I do it all the time with my own trailer running from a 15 amp drop in my workshop, have done it for years with Coleman, Carrier, and Dometic branded A/C units, and will continue to do it whenever the situation calls for it. However, if the A/C in question was a 15,000 BTU I'd only expect success if the source circuit was rated for minimum 20 amp service.
