i borrowed an older model, only cons the ramp was junk bent it up. the tounge is very short makes backing difficult.

 

I have the 2 bike walk up version. More pros than cons but you need to be aware of 2 things in my opinion.
1. Get the ride up version - trust me on this. The ramp for the walk up is ridiculously skinny. If your rear end moves at all on the trailer you will have a tough time getting both tires lined up to unload.
2. Loading a small bike on the right side could be done alone but an 800 lbs bagger is a different animal. Try doing that on the left side when you have to get around the wheel and unless your 6 '8 i dont know how it is done. Even in the Kendon video that part where the guy navigates around the wheel is conveniently cut out!
3. Pulled a Street and Road glide and space between the fairings / handles was maybe 2 inches. We had those bikes strapped down tight but at highway speeds there is still some sideways movement. They never touched but it will keep you looking in the rear view mirror

Oddly enough the Kendon got more compliments than our bikes at the camp site. Pulls like a dream and it is built to last. The ride up conversion kit will be the next purchase

 

Sorry -I guess that was 3 things, not 2
