2016 Greyhawk 29MV very hot this summer

My only concern there is the electrical system in the Greyhawk's are 30 Amp.
My understanding is when an RV has two A/C units, they usually are set up with a 50 Amp system.
Easier for me to run a dedicated line, rather than upgrade the whole motor home to a 50 amp system.


I am not an electrician or an electrical engineer, so more knowledgeable people may have better or more accurate info.

This is very true. You need to size the amp draw on both units so they do not exceed 30A total. The newer Jayco Greyhawks shipping with two A/C units come with a power-management system to ensure the combined usage doesn't exceed 30A. It'll turn something off, for example one of the A/C units, if someone fires up the microwave.


Or, like you said - just run a dedicated line.


Apparently upgrading an RV from 30A to 50A is not super easy to do either.
