Message: [QUOTE="Charles, post: 1308202, member: 103"] Today I had some small trusses and a small bundle of framing lumber on a 25' gooseneck. I think it was like 10 or 12 16' trusses, 40 2x4x16 and 12 2x6x10 IIRC. Not much, but something. The trailer has a tare weight of 6750. Truck is a crew cab long bed on 35's, whatever that is. Probably around 8000. I was pulling this smallish load around the lake from 75 to 575 in ga which is very hilly. I ran into an issue I never have before. The truck pulled so strong down low that it never really came out of OD much. I would be running uphill, passing people in OD at 60mph, which is about 1500 or 1600 rpm or so. The truck was perfectly clean and pulling perfect. Passing cars uphill, lol. The weird part was that it was making so much power and burning so clean in the 1400 to 1600rpm range that it was driving the 38R (with the 1.15 A/R housing no less) to surge..... a LOT..... I did not know a 38R would surge on a 7.3, much less with a 1.15 housing.... but they will. The truck was so strong and making so much exhaust drive at 1500 or so rpm that it was driving the 38R into surge. Thing felt like it had 900 cubes. Had that deep harmonic sound almost like a 3406 or an N14. I'm telling you guys, the 200 is a force to be reckoned with under 600hp. The only sacrifice is idle. And that's a price worth paying considering how nice the idle can be with some attention. [/QUOTE]
