Jaybro,
Welcome and congrats on the (possible) new rig!!!
As for what wd bar rating to go with, know that the “brochure” dry tongue/hitch weight (tw) does not include the weight of the propane tanks or a battery on the tongue. Those add ~120lbs for 2-20lb tanks and a battery, or ~160lbs for 2-30lb tanks and a battery. For new rigs it is sometimes tough to estimate the loaded tw, not knowing how the rig will be packed. A 800lb bar may work, ut as others have mentioned it would probably be best to go with the 1000k rated bars to be safe.
As for which model wdh, that’s a loaded question!!! Lol
I would also agree to go with the 4 way Equal-I-Zer system over the lower model. Know that when (not if! :
you get a bigger rig, the wd bars are not able to be swapped out on the 4 way system. So if higher rated wd bars are needed, a complete system will need to be purchased.
The Reese SC system, or Dual Cam system are both excellent models. The trunnion style head (both models) does allow a little more fine tuning for the hitch head tilt vs the 4 way system. And you can buy different rated wd bars for a new rig down the road, keeping the rest of the system.
You won’t go wrong with any of those three models!!! They are all very good!!!
The Husky CenterLine system seems to be a good system as well. A buddy has been happy with his, though it’s his first wdh so he has nothing to compare it to.
The Recurve R6 also has good reviews.
Blue Ox is an interesting system that some are happy with.
Depending on what your loaded tw ends up being, the Anderson system had good reviews. But reports for rigs with a higher tw, the Anderson may not be able to transfer enough of the required weight back to the front axle.
If needed, follow my signature links for a ton of wdh info.
Don’t hesitate to ask any other questions, both before and after the purchase, even if it’s regarding accessories.
Good luck on the new rig purchase!!!
