I have my Honda XR400 on the front hitch carrier. Only slight headlight blockage but im not normally driving at night. I have a boat behind me and wouldnt want to add any more weight to my already heavy rear axle. Water & oil temperatures are increased by 10-15deg F with the bike on the front and cooling fan comes on more often when climbing long hills. One nice thing about it being up there is that its completely out of my way if camping when i dont want to unload it. Having it at the back i imagine i would always unload bike/remove rack, this isnt necessary when on the front.
