K2500 and 12,500 lb Keystone Raptor 3712

I had a 3612. Pulled it with a Dodge Ram 2500 heavy duty, Quadcab 4x4. No problems with the Ram in over 110,000 miles of pulling. I did install 5,000 airbags in the rear to level because of the pin weight of a Toyhauler. Pulled it in Mexico over grades you will not find in USA. The only other upgrade was drilled brake disc on the front when it came time to do the brake job to the Ram. The only problem I ever had was with the triple axle setup; the rear axle scrubs the trailer tires and causes failures. After 11 Maxxis tire failures I upgraded the 15" rims & tires to 16" and used LT tires. Problem solved but then moved on to a DP Motorhome & car trailer or toad. Our Keystone was a 06 and they had delim problems which were repaired on warranty at the time. Look the sides over and ask present owner if they have had any problems. Believe they had the delim problems addressed by 07. Also I used a 19,000 lb Pullrite Superglide hitch. The hitch really takes a beating and one area I would not short cut. Good Luck!
