Honestly, I've tried many different setups over the years and the Rockies are no joke when you're pulling 7,000 pounds. You really need that mechanical friction to stay stable. My pick is definitely the Equal-i-zer 4-point Sway Control Hitch 10k/1,000 lbs. It's usually priced around $650 online, so it fits your $800 budget perfectly with cash left over for gas.

• Built-in sway control means no messing with extra friction bars
• It's a tank when it comes to mountain winds
• Easy to back up without unhooking The Andersen is a neat design, but in my experience, it struggles with heavier tongue weights in high-altitude gusts. Go with the 4-point setup for that peace of mind... you wont regret having the extra weight in the hitch itself when things get hairy. Let me know if you need help with the initial install steps once it arrives!
