Backcountry or MTB Point to Point in New York or New England with 11 year old

Hi Forum - Anyone with recommendations for a NYS or New England point to point route with camping for two adults and two 11 year olds kids. The kids are competent trail riders and can ride any intermediate trail and some most difficult trails- the adults will carry most of the gear. this is their first bikepacking venture so we want to make it fun for them. The ideal trip would 3 - 4 days of 20 - 25 miles a day - closer to 20 if there is significant climbing. We are considering the Rhode Island N/S trail, but I was told there is a lot of paved sections and a bit of hike a bike. the guide book seems out of print and I do not know for certain. Any help on that would be appreciated or other trail suggestions welcomed and appreciated.
