I recently just bought a 1236 and own a Wrangler Rubicon and had the same concerns about topping with the hard top on. I purchased my boat from someone that has sold aluminum boats for over 25 years and he showed me how to rig it up properly. Basically he put two pieces of foam on my roof and the put the boat on right side up. Then I used ratchet ties threw the doors and some rope in the font and back. I drove over an hour at 65-70 miles an hour and the boat did not move. I was skeptical at first and check it many times. All the lakes by my house are only a mile or two so I am confident in this solution. The next step will be to figure out how to get it strapped to the roll cage when the soft top is down. I attached a picture to show you what it looks like.
