Love mine! There was a major redesign after the initial MJR and it was a huge improvement on a great product. I got one of the first new design racks and I sometimes prefer to load my bike on the MJR instead of in the back of my truck if I'm going to be doing any tuning since it's a great bike stand as well. You won't be disappointed unless you drive a smaller lighter vehicle then you might see some tail dragging since it will put a good load on the back of the vehicle.
Ret you might want to consider running the tie down to the bumper of your truck. I found by doing this it makes the bike feel even more secure since it eliminates any free play in the receiver.
------------------ I ride, therefore I crash KTM 360EXC
i had 1 of these, i liked it pretty well exc. that i had to do a little engineering with a rat-tail file to get it to line up, & it leaked a little fluid & i had to add some. it's a complicated setup, but once you get the hang of it, it works ok. i added booster springs to the vehicle (ford explorer) to get the nose down. that helped a lot, & even made the pig handle better unloaded. i sold it when i bought another pickup.
