The heavy duty plastic car ramps have a 6 1/2 inch lift, I need at least 8 inch to level my Roadtrek RV in the driveway. The cheaper metal ramps with an 8 inch lift do not appear to be strong enough for my RV, a converted Chevy express cab and chassis.
So I am looking at a DIY wood ramp which calls for 2X12 to drive up on. I do not have 2X12 but have access to free 2X6. My question being is 2 2x6 going to be significantly weaker than 1 2X12??
