  1. I have a 2015 2500HD 6.0 gasser. I bought a Diablo tuner and used a stock tune and added a pedal box. That helped a little but not worth the money. Then I had diablew do a custom tune for me and that really lit up the truck. I had him do a 92 octane tune. Not towing the truck is how I would have expected it to be from the factory. It improved gas mileage just a skosh. I went from 11.5 mpg with mixed driving to 12.5. I asked diablew to maximize towing performance, so not sure what he did, but it wasn't maximize mpg. The towing performance is better. I haven't towed enough t
  2. I had this installed on my 2015 Chevy 2500HD 6.0 gasser for a year. I finally got a custom tune and no longer need this. This pedal box does a great job of improving throttle response. I got tired of flooring it every time I wanted to go faster. This does the job. It does nothing but change the signal going to the ECU, so no power boost. Just feels better. $200 shipped. (sells for $299 new). Tom
  3. I got an intune i3 platinum and went with the stock 93 tune. It improved things but I still had to get a pedal box so I wasn't flooring it all the time to get moving. Then a nice fellow recommended I contact diablewtuning.com. I did. Since I had the i3 platinum, he could help me out. So I did a data log and sent that to him. He sent me back a custom tune. Holy crap! I had to pull the pedal box because I kept squealing the tires. This thing is now performing as I would have expected vs. being a giant, 2 ton pig. I'm only 90 miles into this diablew tune. Once I hit 150 mil
  4. Get a bigger truck. You are approaching DRW territory with that trailer. 2x a year or not, your truck is way overloaded with that trailer.
  5. You're going to be overweight pulling a 14k 5er.
  6. I'll snap some pics later today. My 2500HD 6.0 gas does fine with 11k. It likes to spend time at 4,000 rpm and gets about 7.2 mpg. The 6.0 is bullet proof so I think it will hold up fine. What truck do you have? My 2500 has 2,738 lbs payload and with the 5er hooked up and loaded for camping, I am at 9,500 lbs on the truck. 900 below RAWR so not too concerned. But a 14k 5er would overload my truck. I put in a Curt hide a ball gooseneck hitch. Fairly easy to install and works great. The B&W is a good option as well. I also run Firestone airbags with the remote. I run a
  7. I do. On my 2500HD gasser regular bed. 11,000 lbs 5er. I have the coupler set up to move the trailer forward. This helps the ride a bit. I can still do 90 deg turns. Sure is nice to have a 35 lbs hitch I can hang on the wall when I don't need it.
  8. According to Newmar's brochure from 2003 (https://library.rvusa.com/brochure/2003asttandasfwbrochure.pdfhttps://library.rvusa.com/brochure/2003asttandasfwbrochure.pdf? Dry weight: 10,187 Dry Pin Weight: 2,037 GVWR: 11,900 With your cargo capacity, this could work nicely depending on how much stuff you put in the truck. I'm planning on buying a 5er with about the same specs to pull with my 2015 2500 HD 6.0 4x4 65' bed. I have no experience with 5er hitches. It looks like from the pics in the brochure that the front of that trailer is not short bed
  9. What is the year and exact model of the trailer? Also, what does the yellow sticker on the B pillar of your 2019 truck say is your cargo capacity?
  10. Coolio! What size 5er are you looking at getting? BTW, the gooseneck install is fairly easy if you are looking to DIY.
  11. I installed a Curt in my 2015 2500HD. Go with a B&W or Curt. Both are good. While you're under there, install air bags with a remote.
  12. Holy crap! That 6.0 will be a beast with that Magnuson. I think I would rather have an oil burner for that much money, but it would not be the same as your 6.0 with a Manguson. Let us know how you like it. I looked at the install .pdf and it looks fairly straight forward.
  13. Excellent upgrade. How do you like the 6.0 + 14,00 lbs 5er combo? I have a 2500HD w/ 6.0 and I'm looking at 5ers in that range. Maybe a little lighter @ 12k lbs.
  14. I cut up a cookie tin for shims. Not the most elegant solution but it worked.
