Interesting...?
"Do not put any VersaHaul carrier on the front end of any vehicle. All VersaHaul carriers extend beyond the maximum allowed distance for carrying such weight on a front end hitch. Failure to observe this precaution may result in catastrophic damage to your automobile and/or VersaHaul carrier."
We carry a small step-thru scooter on occasion, weighs~350. I built our rack and its as tight to truck as I could get but I don't understand the comment by Versahaul.
Extra weight up front could adversely effect though generally on a full size truck not like the frames gonna collapse? AS far as the rack it wouldn't see more load than if mounted on rear. Curious
When I mounted ours I put the scooter on some (sketchy) blocks and a lot of eyeballing to see where it would set on truck and issues that might be avoided or at least aware of. Mine was blockage of turn signals from certain angles so mounted lights. Should be able to guesstimate what might be effected.

This was at Kings Canyon Ca., ours is truck on left. The white truck were some folks from Florida traveling across the country (with thier scooter)
