Looking for ideas with bedrail clearence on 2013 Ram 2500

There are ways to raise the trailer which looks like what you need to do. One is to get a equalized, which goes between the springs, which is taller. A more expensive alternative is to install "Correct Tract" which will raise the trailer about 2 inches. This may seem like overkill but it allows you to align the trailer axles which may be a benefit. If you had been to the Heartland Rally last month you could have bought a Correct Tract system at a bargain. The new Heartland trailers have this system factory installed.
