Achieving level tow with Ram 3500

Thanks for all the responses and good input. I'm more confident that we'll be able to get reasonably close to level and maintain 6" clearance. I posted personal message on Forest River forum and got more info on Correct Track which appears will provide about 2" of lift on the RV if necessary. Don't know if PrimeTime will have issues with it. Another entry here that the auto level air suspension will lower the bed about 2 inches suggests that these two can get nose down significantly. Scheduled to take delivery 3/29, will post results after that.

Thanks again.
