My 6.5 with a 185/385 was never as slow as Turtles 6.5! Then again, I believe he has an auto version, I had a NV4500 with 2000 lbs less gcwr than him.......usually found I could go down the road at 15-16000 lbs with out too many issues. Thats upwards of 4000 lbs OVER my gcwr, and over the auto version by 2000 lbs. I went up 15% grades in 3rd gear, ie gear below direct in Yellowstone doing 35 at 2600 with throttle to spare. Could not pull those grades in direct mind you! But i was much faster than I was 9 years earlier, pulling the same trailer, 1000 lbs lighter with a higher rated POS 454/TH400 combo! I was in first gear doing 25-30, waiting to stall out!
As noted, a non turbo at 10K feet with not do as well as the turbo rig! I can not imagine the OP being in the mid teen gcw relm as I was. 11-12K yes, but 14-15K+ not! Also, the trailer he is looking at is 7.5' wide, vs mine at 8'. I also doubt it will be 11' tall, probably 9-10', so frontal area will not be as bad.
I doubt there would be as much issues as people saying!
