Expert Reply:

This will depend on the hitch used and the height of the trailer coupler. You want the trailer to be as level as possible. We have a page on calculating hitch height and coupler height to help you find what ball mount would work best.

Most light duty trailers are 16-17 inches in coupler height, so we recommend ball mounts on the hitch pages that will give that particular vehicle 16-17 inches on the ball mount. The ball mount that provides 16-17 inches height for a 2008 Hyundai Entourage is part # 2753.

I have a fairly steep driveway. Before I purchase a trailer I would like to figure parameters for when my hitch might bottom out. I suspect it has to do with the angle of the driveway and length of trailer from coupler to axle? An illustration on what to find to figure out would be ideal.

This is a difficult question to answer because of all the variables involved. There isn't really a set formula or diagram you can use for it. If bottoming out is a big concern, your best route will be to actually mock up a trailer setup with your tow vehicle on the driveway to see where it bottoms out, and what needs to be changed to prevent it. The driveway angle, actual coupler height when hooked up (the rear of your vehicle will likely sag a bit upon hookup), angle you actually come up or down the driveway, etc will all factor into play.

@ChrisR I am in a similar situation and have made a pyramid shoring set that will decrease the angle, it takes an extra step to place them in the low spot but works fine for raising the trailer axle 4''

Curt recommends the use of 250 ft/lbs of torque when tightening the nuts of their hitch balls with a 1 inch diameter shank like the part #C40034 that you referenced. The general rule is for a 3/4" shank tighten to 150 ft/lbs For a 1" shank…

Measuring to find the right rise or drop needed to tow the trailer level is easy. First park the truck and trailer on level ground and uncouple the trailer from the truck. Use the trailer's jack to make the trailer level. Measure from the ground…

We don't have a combo of the Curt Hitch Ball #C40008 and Curt Ball Mount #C45340. The ball mount is extremely heavy-duty, rated up to 17,000 pounds. I think it's safe to assume you don't have a torque wrench rated up to 450 foot pounds…

As you've figured out their not listed by lumens because the manufacturers do not offer that information. It has to do with them being DOT compliant and they list their brightness by diodes not lumens like you see in flashlights. I'll be more…
