Ride the wilds NH advice

Originally posted in eastern riding section and realized that section is more for WV and TN. Going up for Memorial Day weekend. Got a cabin at Coleman State Park in Stewartstown in Coos County that we can just roll right out of the campground. Looking for some input on places that are must see’s, some neat places to stop for lunch, local advice and suggestions for 2 day trips. Travailing with 2 well equipped 800S one Arctic Crap trail and my daughter on a raptor 350 and possibly a 1000 4 seater that leads to my next question. Do I have to worry about a 64" width of the 1000. I came across some NH sites that say 62" and some that say 65" width limit. This place sounds too good to be true with 1000 miles of connected trails, able to roll down the streets and thru town legally, My 14 year old can also drive legally but I have never came across anyone that has gone here though. Does this place actually exist.
Thanks in advance.
