The Catalina 22 National Sailing Association -
Blog - can give you better Cat 22 specific advice. I would join to learn more about your boat. I found the Mariner Class Association to be a godsend in learning my Mariner, well worth the $15/year.
All up your rig is going to weigh close to 3500 lbs. Your tow vehicle needs at least that tow rating, and preferably more. For towing that distance, you will want trailer brakes. Trailer brakes are required in some states for anything over 2000 lbs. You are on the borderline for a tandem axle trailer. Tandem axles tow better, but cost and weigh more.
