I looked at the brochure for 2002 Friendship model 8362, and the specs are 330hp cat 865 torque, 27910 gvwr. You can get all the brochures for all years, the link is:
www.gulfstreamcoach.com/towable landing/brochures
They have changed the site, but go there and find the model you want to research, and click on it's link.
Good luck!
