Forgot to add that I went with B&W Companion Slider based on several threads here, plus I already had their turnover ball gooseneck installed. Very happy with that decision.
A couple of design things I’ve found already...the black flush is on the rear of the trailer so I have to fold the storage rack down to access it. The spare tire is mounted to the storage rack, so folding it down places the tire close enough to the ground that I’m concerned about scraping the tire on the ground, especially on a sharp hill or parking lot entrance...I may work on a different way to mount the tire on top of the rack.
