Question:
My trailer is about 8,500 pounds loaded, so I'm under the InstaLatch's 10,000-pound rating. The brochure says 850 pounds of hitch weight before we load it. Is that enough information to know whether the 6-inch drop mount will work?

Hello Curtis! You'll need to check your loaded tongue weight to know for sure. The BTBRV InstaLatch Ball Mount # BTBRV011 is rated for 10,000 lbs of trailer weight, and has a 1,000 lb tongue weight limit. It is certainly possible to be under the towing capacity and still exceed the tongue weight rating.
I recommend using the Big Truck Big RV Tongue Weight Scale # BTBRV44FR or # BTBRV014 to check your actual tongue weight once the trailer is loaded. Both measure up to 2,000 lbs, so you'll know whether you're within the ball mount's capacity.
What kind of trailer are you towing?

I am a Direct Store Distributor, consistently towing 16k, the tongue weight scale is critical for me to insure I don't exceed maximum tongue weight, you can be well under your maximum tow weight and still significantly overload your tongue rated maximum. The scale lets you know exactly how your distributing the weight.

I bought one of these scales. The one in the top picture. It worked great. Once you get the tongue weight correct, you can put it in safe storage for the next time. I marked where my car needs to be and I load the car to the same point each time. I thought about buying a hitch that has the gauge built in, but reviews stated they break a lot. Constant up and down on the weight as you drive down the road. Once you have you tongue weight correct, no need to have the scale on the hitch. Good Luck !!!

It's an enclosed car hauler. Would moving the car forward or backward change the tongue weight enough to matter?
