I keep getting code P0440 or P1441 on my truck. I changed the gas cap already, reset the code, but it comes back in a couple of days. I read that the codes are for small evap leak. My next step is to replace the Purge Volume Control Valve that is attached to the EVAP canister. Is that logical to do next? My truck has 188K on it now.

Yes, replace that valve. Be very careful removing the bolts that attach it to the canister. One of the heads broke because of corrosion and I ended up having to buy a canister too.
