We've had our gasoline version Champion 3100 with remote start going on our 3rd season and it has no issue whatsoever running our rig's AC unit on very hot days or at high altitudes (up to 8500'), even does so on eco-mode.
You could get the Costco version and see if it will perform the task you outlined above on propane, unless there is something different about this dual fuel model, it should power your rig's AC unit on gasoline mode if anything.
I notice that here in Canada Costco is offering the dual fuel electric start model in the larger 3400 watt size only, with the smaller 3100 watt being manual start, gas only. One would think the 3100 watt gasser would easily start & run a 13,500 BTU A/C but I also notice a couple of reviews where purchasers said the one they bought would not. :( Costco Canada's price for the 3100 is $930 Cdn + tax, the 3400 is $1280 Cdn + tax, a difference with tax of ~ $400 Cdn. However, aside from the larger dual fuel having a larger engine and electric start it seems to me that running it on propane and
never putting gas in it would eliminate any carb gas fouling issues, the need for gas stabilizer,
and the need to ever empty the tank for long duration storage, so even though it produces less power running on propane than running on gas this larger Champ may be the better long term solution for many despite it's higher cost.
