Of course it is dependent upon your specific install, but it's easier than putting in. Without seeing your implementation, I would likely recommend you can have an electrician replace the wall charger for a 14-50 at a minor cost. The wires and conduit will not need to be changed but the breaker will and an outlet added, which "should be" extremely inexpensive. I say should be as if you did it yourself, it's less than $50 in supplies but electricians will likely have a minimum fee of around $200 - $350. Then you can take the wall charger with you to your new home and have it installed there.
So if you have an electrician do it and they charge $300, then is it worth the $200 difference (new ones cost $500 but are constantly out of stock) to have a brand new v3 wall charger instead of moving a used one which is maybe an older generation? Just a choice to make.
