Longtime lurker, 1st time poster.
I have the same Passport 219BH (2021) and tow with a Tahoe and the Husky Centerline TS. I got the hitch new off craigslist for a deal knowing it had the 'wrong' 600lb bars and I could upgrade pretty cheap. When I set the hitch up on the Tahoe I get identical sag on both the front and rear wheel wells so I started using it. For me the 'correct' bars would be the 800lb and I always wanted to get them and there is something in my head saying I should still get them but if I am honest with myself I probably never will. After towing all around Colorado for a year, up and down I25 (flat & fast) and over the continental divide multiple times, I70 and winding 2 lane passes I don't have a real reason to change them out. The hitch and the 600lb bars I have worked like a dream. 100x better than the last RV with the chain bars and friction bar. So where I am at is that it is academically correct to get the 800lb bars but I probably never will.
