Not only will Onan 4000 not run 2 ACs, they are installed on 30 amp rigs, which makes it difficult to just add another AC unit down the road where rig also needs upgrade to 50amp service. Go with single 15K AC unit or choose rig with 50 amp service from the get go.
So a single 15k A/C will be fine in a 28ft toyhauler? Still seems to small. But maybe with today's technology it would be fine. All the dealers say it's plenty but I know they are trying to push a trailer out the door and will basically tell ya what you want to hear. That's why I'm asking those of you that actually use them. I highly doubt I'll be dry camping in 100 degree plus weather but I'm sure 90 could be likely. But not a lot.
