Be sure to take a tablet of paper and pen/pencil to make a list of 'reality' stuff needed, and what you find you don't need but have taking up space.
As to towing - not too big of a deal - the PUP will track with your tow vehicle, but slightly wider turns may be necessary, longer stopping distances.
Backing into your sight may seem like a trial to you (why i recommended practicing at empty school parking lot/bus lanes). Place your hands on the lower part of the steering wheel, and the direction you want the PUP to go is the way you turn the steering wheel. Only turn it 'slightly' or you will cut it too much. Go slowly and stop frequently to check progress - or have one of your camp mates be your spotter.
Remember to have checked for low branches on the campsite before backing into it.
Have a wonderful trip!!
