I have no interest in doing research on part numbers from a 2008 Ram. You're grossly overweight and your trying to convince yourself that you're not. If you want to operate that way, that's a conscious decision that you make. The limitations on these trucks are developed by engineers, do you think you know more than those professionals?

That argument only holds true if you assume engineering create the specifications instead of accounting or marketing. The fact is that same equipment is under different names and specifications because is cheaper to stock less variety of parts and have less variation on assembly lines.
