We have three Robinair 34788's. One we have dedicated for the systems with the Bitzer compressors since they use a different oil. I don't know of any issues with the recovery tanks being too small. We did order a tank to swap out when they got full until our A/C consultant told us to use the Freon in the tanks to recharge systems.
i dont have an issue with the robinair tank we had an older machine that only had a 12 pound tank so everytime i used it i had to pump the freon out if i had to remove both compressors on the bus but the new robin air machine is fine
