What do the chassis manufacturers rate their chassis to tow?
Chevrolet literature states any trailer over 1,000 pounds loaded must have its own adequate brakes. Ford literature states that a separate functional brake system be used on any tow vehicle. Ford does not state a weight, but notes that most states require brakes on trailers over 1,500 pounds. Other chassis manufacturers have similar limits. Please check with the manufacturer of your chassis before towing. If a warranty issue concerning braking is raised on your chassis and you are outside their guidelines, be sure it will be used against you.
