I have a 2001 Ramm 3500 diesel that I carry a drz400 on a CycleGear hitch rack on the front. Bike and rack weigh around 400lbs. If I go over a bump hard I get a little slap but it is rare.
Visibility is reduced but still safe to drive. Night driving is harder because the bike blocks a lot of the light. I removed the relay that only turns the fog lights on when low-beam is selected and jumped the terminals with a wire so fog lights work when high beams are on too. This helps but is still not perfect. My plan is to add LED spotlights to the front of the bike carrier and wire in a plug that connects to the fog light circuit.
In hindsight, I would have purchased a carrier that can easily hold a gas can too. I need to weld a platform to hold a gas can on the carrier securely enough for me to trust it on the road.
I really like this setup and recommend it to anyone with a camper and a single bike.
