Yes.
No.

Depending on the 911 and the trailer this setup is going to be marginal at best. Check the towing capacity of the BroncoII and the GCWR including tow vehicle, trailer, 911, passengers and all your stuff plus a tank of gas.

Don't exceed the ratings. Even if you're right at the limits, you may still have handling issues at high speeds. That's a lot of long highways with 75 mph zones. Getting passed by an 18 wheel truck going 20 mph faster than you in a crosswind is going to be an adventure in a Bronco II.

The only way I would consider a trip that long is an a car/trailer combination I had been driving for a while.

Just my two cents.
