I second the compressor cooler/fridge. Either get one small enough to fit in the frunk or a big boy dual zone for the back seat or bed.
I highly recommend getting a 300-500wh battery bank or “solar generator”. It can keep the cooler going all night. Pro Power will zap 1-2kWh overnight in...
Did Portland to Phoenix this spring. Really wanted to do the NV route but didn’t have my adapter yet. Even with it, it’s not doable in my SR without at least one over night at an RV park. Most of the SC there are Gen1 and 2.
I’ve used my adapter to charge at two different V4 stations. They have the adapter built in but are not yet enabled to dispense. Love the long cables at V4!
I don’t ever use for Nav and therefore no preconditioning. Never had a notice issue with DC charging speeds. In fact, I prefer to not burn the extra kWhs if I’m paying DC charging rates.
