I carry 110 in my steer tires and 100 across the drive axle. Those pressures are based on tire SIZE and axle WEIGHTS. YMMV...we travel no more than 3 hours/day at 60-62mph. Leave around 10-stop at 1ish. Allows us time to set up at the campground and enjoy the trip. Do some sight seeing, do some shopping, enjoy the resort we're at for the night. Allows us to hit the road the following morning rested and alert...
Our policy is it's the journey, not the destination that's important...lots to see between Jersey and Florida...IMO, get off I-95 and enjoy the country as you travel south.....Dennis
