Any info on availability of trailer hitch dealer-installed accessory or aftermarket (Reese, Curt, Draw-Tite, etc.)? And other than dealer-installed any experience with light coupler? I would use mine to tow yard waste to the recycle center, pick up mulch, furniture, dirty cargo a few times per year. Current plan is to schedule with dealer @ 10,000 mile maintenance, about 6-8 months from now and patiently wait...
