I’m not sure and I doubt the manufacturer will tell you given liability issues. However, my insurance includes road service and my tires are so darn heavy, I always figured if it happened, I would let them deal with it. I am quite sure your present jack could lift the front with no problem as almost no weight transfers to the front axle with a truck camper (only 9-10% of camper weight on our last two truck campers).
I asked for the rating on a truck site I participate in and am waiting to see if anyone there knows the answer.
