Sonoma is icy cold, the crewcab has never been cold.
Always figured the system just isn't enough.
Wanted to ad an evaporator like a suburban, but never did.

A more efficient Condenser might help in both cases.
I've gotten almost too cold from the systems I've done with an A6 compressor. The first one I did I thought I had it undercharged but the gauges were about where they should be and the evaporator wasn't freezing up.
What are your vent temps?
It could be from too much oil. When you convert to R134a you need to flush as much of the mineral oil out of the whole system as possible. If you don't flush it out you have no way of knowing how much oil is in there. Too much oil will adversely affect evaporator and condenser operation keeping your vent temps higher than they could be.
