I got my Shurtrax All-Weather Traction Aid yesterday. It took about 10 minutes to fill up and it fits perfectly between the wheel wells. I have some bunjie cords holding it in at each corner but am going to get some nice tie downs for it. It definately toned down the bounce factor some on the freeway whoop-dee-doos and makes the rear end feel more stable in all conditions. It did not totally get rid of the bounce on the worst freeway spots but it rides a lot better now. I would recomend this thing to anyone who wants to load up thier rear suspension for a smoother ride and added traction. I am not really sure how the 400 lbs. additional weight will affect my gas milage...only time will tell I guess.
My friend thought it was a waterbed for a dog. Actually if you lay on it it does feel really nice on your back because the water heats up to the perfect temperature. The exterior material is like a soft top on a BMW...very durable looking. We put my freinds 50 lb. amplifier on top of it after we played a party last night and when we got to his house the amp had not moved and inch. I paid about $90.00 on
amazon and it arrived at my door in about 7 days. Here is a link:
