I used a tri-pod and wheel chocks for years. Finally installed a set of JT's strong arms - improvement and I don't have to hassle with the tri-pod anymore.
Purchased all of the items from Tweety’s RV (http://tweetys.com/)

I used the spacer mounts SJ-4011 and the adapter plates (LCI Electric Foot Pad Adaptor Kit - 314597 ) for the rear installation to give me a little more clearance for the t-bolts. I had to remove a portion of the hitch I had installed earlier in the year so I could drill the holes for the rear brackets (what a pain).
