Question:
Hi, would drilling the mounting holes to 3/4 inch take away from its integrity. My existing trailer uses this pattern and I prefer this black version over your white. Thanks, Randy

Expert Reply:
Hey Randy. Drilling the 5/8" holes out to make them 3/4" is going to effect the integrity of the Black Demco Trailer Coupler item # DM69FR. I recommend going with the White item # DM99VR which already is pre-drilled for 3/4". It has the same 4-1/2" mounting pattern between holes.
If you have any additional questions feel free to throw them into the comment box below and I'll be happy to answer them.

Hey Randy, did you decide to go with the white trailer coupler that has the pre-drilled 3/4 inch holes? I'm curious because it might help others who are considering a similar switch.
