We are having the same type of issues, I have a 98 P30 chassis with an Evans system.
My Chevy dealer is today finishing the installation of my new Condenser and the Trinary switch (discontinued part).
My condenser was really old and nevertheless before it leaked was able to cool the place down. By the way the condenser is also used as an engine oil cooler on my year of manufacture.

On the other raised topics, you can install a bypass valve (I did), but it's not doing much because I repaired all the vaccum switches so everything opens and closes on demand.
Depending on the rv manufacturer you may have to watch out for the bypass (how you install it) because in my case the antifreeze is also routed to heat the hot water heater, then the floors out back and a secondary heater with blower under the bed.
