Some science regarding towing

Says similar things I learned when I first started towing in the late 70's. No trailer bigger than 2x the GRAWR, or max gcwr is 2x gvwr or 3x grawr. Then you have a trailer that is not too big per say for the tow rig chassis. From here, you spec the drivetrain to YOUR performance specs, not some engineer/J2082ASEA specs which are totally useless for the type of towing I personally do. IE I go up grades to 30%, there spec is a minimum of 12%, I want speeds of 40-45 on a 5-6% grade, theirs is 35min on a 4% grade. So my performance specs are probably way the heck tougher to meet than those puny useless specs!
