Sometimes a fear of heights can contribute to other fears, like aviophobia. Cognitive behavioral therapy (CBT) is sometimes helpful in treating cases of aviophobia. Aviophobia is a fear of flying.
Re: Increase towing capacity? Postby Z15 Â» Jul 01 2010, 5:59am. With that kind of weight you need to beef up the suspension big time. Air bags are not going to cut it, you need heavier springs, HD shocks, Load range E tires, bigger brakes.
The minimum tow capacity you're likely to need for two horses and the trailer is 5,000 pounds; a 6,000 or 7,000 pound towing capacity not only gives you some breathing room, it also makes for a safer and easier towing experience because you're not up against the limits of your vehicle.
