Round Trip or one-way? If RT, you should be able to find a place to recharge, hopefully.
I do occasional long-distance commutes,
PEDAL POWER. My longest has been 200 miles
one-way. I try to avoid pulling a trailer. I'd much prefer to load down the bike, or a small pack. But, for some things, a trailer is handy.
However, I've realized that I can store some items at the end of the line. So there is no need to carry things like clothes back and forth. Often one of my last tasks is to stop by the laundromat, and clean my spare clothing for the next trip.
Anyway, evaluate your needs to see if you can economize a bit on what needs to be carried back and forth. Then evaluate whether you have time & resources to do the ride.
Also, learn quite calm roads vs shortcuts
