Putting the bike at the back of the van can unsteady the van... You can get racks that secure to the front of the van tho... Personally, I'd carry inside the caravan you can turn the handle bars so access is easy, then as said remove and secure outside when not needed, use blankets I between bikes and fixtures to secure against scratches....l IMO that's what I've done did do

Regards tt, failing that up on roof rack, but NEVER on the rear of the van, not strong enough and personally I wouldn't want to drill through can only help with water ingress/damp  2010 TDV8 Bali Blue........ "Alive Tuned"
