  1. ECU module programming guide using FDRS

    I agree, looks to me like what is available in FDRS today are the modules that updated with 2.5.1. I'm thinking of ignoring the DTC in the IMPA that cropped up - it relates to network communication with the GWM....and knowing a GWM update (should) show up in FDRS later.
  2. Any update on a Trailer TMPS system?

    As promised, a bit more on my experience. This post is all about my specific truck (2021 King Ranch 601 Power Boost, Max Tow, 360 Camera, Blue Cruise Prep, built in Feb 2021, OTA update 2.3.0). For pro-trailer back-up, it came only with the yaw sensor (no stickers). When I ordered the truck, I...
  3. Any update on a Trailer TMPS system?

    Hi all. Huge thanks to GChurch for your contributions. I got my harness today and wanted to give a quick update. I will try to get some pics and a bit more comprehensive comments later in the week. Overall quite straightforward following GChurch’s steps. It is very handy to have the new...
  4. Any update on a Trailer TMPS system?

    I ordered the bumper harness mentioned in this thread and it is finally on the way to me. So I will let you all know how it works on a Job 1 King Ranch PowerBoost later. Maybe we need a thread for harness orders…..mine would be: placed 2/12/2022, notified of back order 2/14/2022, shipped...
  5. Trailer brake not working

    I had the same problem this past weekend. 2021 KR Hybrid, Rockwood MiniLite trailer. Lights were working fine, trailer brakes nonfunctional with a “no-trailer” message on testing the trailer brakes. I was leaving a campground, stuck in the mountains 3 hrs from home. I managed to get it...
  6. Trailer Right Turn Lamp Fault

    Just looking at the picture, the ground pin does look corroded (the pin with the green and white stuff at the top left). You could try cleaning it up with a brush and/or some electrical contact cleaner. If that helps some dielectric grease on all the pins would prevent the corrosion from...
  7. Feedback Requested on Limited w/ PB Towing Inbound Jayco Travel Trailer

    I'm a bit with the others, that is a pretty big trailer for the payload. If you want to get as close to payload as possible, my suggestion would be to minimize the tongue weight by reducing weight forward of the trailer axles / moving weight to the rear of the trailer: * Smaller or single...
  8. Payload vs Max Tow

    Awesome HDPP, congrats! I'm jealous, the hybrid is non-negotiable at my house.
  9. Towing Specs Consolidated Document - Bumper vs. Class IV vs. Tow vs. Max Tow - UPDATED DOC v4

    I doubt it will make you feel any better, but if you look at the 2019 towing guide, the Ranger is only good for 7500 pounds if it has the Towing Package (53R). Without the tow package, the Ranger is only good to 3,500lbs.
  10. What are the heavier options to avoid to increase payload?

    The power running boards really hurt (~60 lbs in last gen). That and dropping the power tailgate would be what I suggest are the biggest confident payload boosts with a 502A lariat. I suspect there might be weight savings in 18” wheels too, but I could never pin down the savings, and seemed...
  11. What are the heavier options to avoid to increase payload?

    Good point about the 4x4 options. Skid plates are the key part for me for the snow, and I’m assuming there isn’t much weight difference between a 4x4 with Skid Plates and an FX4 .... FX4 seems to get you different front shocks (should be negligible weight difference) and a software mode (better...
  12. What are the heavier options to avoid to increase payload?

    Sorry, I don’t have any info on the power step. I’ve just been assuming the heavy part is the steel for the step (hence assuming the ~ 40lbs), but you are right, could be more. Unfortunately, in Canada we can’t order 600A (Base King Ranch) or 700A (Base Platinum), we only get the “x01As”...
  13. What are the heavier options to avoid to increase payload?

    Putting the bikes on the back of the trailer helps for sure. Also, I try for absolute minimum stuff in the bed of the truck (even if that means somewhat messy/dirty things in trailer compartments). On your question, in high trims, I think the best option to drop is the moonroof. I believe in...
  14. Towing test with 2021 Powerboost F-150

    I think it is important to keep in mind the Heavy Duty Payload Package is only available on the 157” and 164” wheelbases. So there is no such thing as a HDPP 145”. It is not provable in any ford specs I’ve seen, but all the photos I’ve seen of a “HD” frame sticker on a 145” wheelbase have been...
  15. Building a Tow Vehicle

    I tow a similar trailer (Rockwood 2304KS, ~6600# GVWR), which I currently pull with a 2011 with 6.2L with Max Tow. Ruckus makes a lot of good points. I especially agree with the comments about the 5.0 revving to work....my 6.2 is a stronger engine in size and torque but it still has to rev...
  16. Towing capacity of 2021 F150

    Max Tow also includes the stronger rear axle with a higher RAWR which is handy if you end up with a bunch of “stuff” in the bed while RVing.
