Hi Peter and welcome to the Jayco Owners Forum! We also had ordered our tt and it was hard to have to wait for delivery!
We have the 28bhs, so I'm not sure if the doors are the same, but here are the measurements for ours (measurement taken from inside lip with door open)....
Rear Door - 38 1/2" wide and 9 1/2" tall
Front Doors - 23 1/2" wide and 15 1/2" tall
