That's a little bit of a conundrum because a 40 amp breaker and wires shouldn't be used with a 50 amp receptacle, and a 30 amp receptacle is not rated high enough to charge at the full 6.6 kW your Pacifica is capable of.

You could install a 30 amp receptacle and buy an adapter to use with your stock EVSE. The stock EVSE will limit itself to 12 amps, so no risk of overloading a 30 amp circuit. You'll be limited to ~2.9 kW though instead of the full 6.6 the van is capable of. The other sucky thing is that RV hookups tend to only have NEMA 14-50 receptacles for their 240v service, so your adaptor wouldn't work there.

Alternatively you could buy an EVSE and have it hardwired to your existing 40 amp electrical run. You'll get full charging power by doing so, with the expense of having to buy another EVSE and complete the connection to the existing wiring.

If it were me though... and this goes against code and would blow up 120v appliances if you connected them... I would simply wire a NEMA 5-20 receptacle to the 240v circuit and plug your EVSE into it. I'd put a red warning sign on it that says not to use the outlet because it's 240v. I'd have a fire extinguisher rated to put out electrical fires nearby in case someone still decides to disconnect your EVSE, not pay attention to the warning sign, and plug in a 120v appliance. I'd do this because it's electrically safe so long as nobody ever tries to plug a 120v device into it, and it's the cheapest since the only expense is a $3 receptacle. I'd get a single receptacle instead of dual just to minimize the temptation to plug anything else in.
