I was reading about Tip Over and Center of Gravity on trucks. I found a Center of Gravity Rating on my Tender which was 70 inches for a safe DOT Rating. The formulas take a lot of things into play as far as hight, how wide, axle spacing, weight ect. With this in mine my Tender is 10 ft 3 inches high with the tank bottom up 43 inches from the ground. But when you take the measurements and weight of the truck(17,500lb), tank(11,600lb) ect my Center of Gravity is 53 inches much below the 70 inches DOT figures is safe. You take that center line height draw a triangle and the truck would allmost have to be on a 45 deg angle sidways to tip over with out taking cetrifical forse into play. That is with a full or 1/2 full tank also. The 8 solid 2'X 2.5' baffle chambers with 1 plate down the center keep the water from sloshing in a turn but the water can shift slowly thru the 2-4" venting/drain holes front to rear per chamber and one at the front & rear on the center one if you keep it on a angle for a while. I found this information on a Jeep site on the net and by what I saw the jeeps realy don't have much more room then my Tender does on the tipping over part. I feel better now knowing what my tip over point is and I think it would slide befor it would tip. I sure know I would never try to drive on a side hill of 45 degs for sure with it!! Mark H.
