Gents...I've read several threads regarding 150s and 5r's and I pretty much understand the weight issues associated and appreciate the information you're passing. My question is this...is it possible to increase the cargo capacity by adding a leaf spring or inflatable leveling devices to keep the truck from squatting under the weight and still be legal? I'm pulling a 1/2 ton rated 5th wheel (6500 dry). No prob with towing, but the pin weight is the issue. I've installed heavier load tires and it doesn't bottom out the suspension, so I was wondering if I could somehow increase the load capacity with an after-market solution...thanks!
