Trailer: 2021 Vibe 21BH (5200 dry, 7500 GVWR)
TV: 2019 F150, Twin Turbo 3.6 ecoboost, 6.5' bed, 157" WB, towing and payload packages (7050 GVWR)
Outside of towing our new Vibe home (45 miles) about 3 weeks ago I have not towed it. I have been "making it ours' and starting to load it for a future trip. I have also replaced the Castle Rock tires (ST205/75R14D) with Goodyear Endurance ST215/75R14D). I have not scaled either the truck or Vibe yet, but will. I do have a tongue weight scale ordered. The dealer installed an E2 (Fastway) WDH. I know I will have to re-check/re-adjust the hitch once I get the trailer load to travel weight. I have watched a number of videos and read a number of WDH setup procedures and believe I know and understand the basics of the correct setup.
But there is one component of the hitch setup that I do not fully understand and that's the 'Spacer Rivet' and washes (see photo below) used to tilt the hitch head Ball back towards the trailer. So here are my questions:
- What is the reason/need for tilting the Ball?
- What is this adjustment (adding/removing washers) for?
- If I Add washes what is the effect on the Hitches operation?
Relative to the number of washers to use, the E2 Manual says, "Start with 6 spacer washers for longer wheelbase tow vehicles like pickup trucks, and 5 spacer washers for shorter wheelbase vehicles like a small SUV.
" The dealer put 4 washes in ??? when I have a F150, and a 157" WB rather than the more typical 145" F150's with the 5.5' bed.
So I am hoping that some of you who understand the setup on the E2 hitch can explain to me what this 'Spacer Rivet & washers' adjustment is used for and what would indicated that I would need to add or remove spacer washers?
Thank you in advance for sharing you knowledge.
