Same situation here with my wife’s 2021 Model 3 and just took delivery of my R1T 3 weeks ago. She drives more than me but so far we just use the NEMA 14-50 outlet in the garage with a 50 amp breaker and the portable charger from her Tesla. I bought an adapter for the R1T and just alternately charge whichever vehicle needs more juice at the time. There are several stores in our area that offer free charging while you shop so I use those for the truck quite a bit but we are never hurting for range or anything. Depends a lot on your needs but the one charger is more than fine for us. Grizzly-e makes a “Duo” charger than has two cables to simultaneously charge two EV’s at a time if you think you really need it.
