I just bought one using the code from Mntsnow Here

 

I guess I should state that I've never used the second one.
However, I bolted mine to my trailer floor and rode my bike into it and it stood straight up no problem, and was quite stable. And no way for it to roll out either.
I bought my bike in KY and trailered it home because it was freezing and raining. Otherwise I'd have forgone the chock and rode it home.
The reason I didn't buy the second one is because I had a coupon for the first one.
But either way, I'd have been happy because I'm just not that hard to please.

 

I like the looks of the second one. Having recently changed all the fluids on my FLHXSE, I can tell you that I can't get my jack under the bike to level it, and the fluid catch pan. A wheel chock is a must for the next time.

At $70 full price, that's not bad. And I'm sure it can be had for cheaper if I try hard enough....

Giving this some serious thought!

Def go with #2, im going to bolt mine to the floor once I determine where its going so I can eliminate the long bar in front which will surely turn out to be a trip hazzard.

 

I bought three of the first ones three years ago for my enclosed trailer and my lift table. They have worked great!

 

I bought a couple of the second one and then spent $20 on decking and t-nuts and now I don't have to bolt them to anything. I can move them around where I want and even put them in a trailer if I want to.

 

Thanks for the codes b17467 and Turn8a.

 

I have four of the first ones. One was in my cargo trailer, one on my lift table, two on my flatbed trailer. I don't even strap the bike to the lift table anymore - the chock holds that well.

If you are vertically challenged or have problems backing up, the second is probably easier. It takes a bit of umpf to get them out of the first one. My wife is an accomplished rider, but she can't comfortably (or maybe at all) un-chock her SG from one of these.

 

Eather one is a winner, i use the first one.
