Bought one of these this weekend at Joes, my SuperCrew really likes the extra weight back there. Soaks up a lot of the little bumps that you normally get from expansion joints etc, plus it doesnt dive as bad under braking.

I am going to go out and get pictures in a minute.

 

The sack is a little smooshed up to the front in these pics due to some serious brake mashing traffic on my way home (blanking Thanksgiving traffic):

 

is that full of water?

what keeps it from freezing solid? anti freeze?

 

yeah it is full of water, it just freezes. you leave room in the bag for it to expand, the bag is a really tough vinyl, think truck tarping or heavier.

 

Hmmm, that looks like a good idea...

Sorry, the link is not working for me. Approximately how much do you think it ways, and how much did it cost? Thanks!

 

It should be about 300-400 pounds, i plan to drop the water out of it when i tow or haul my snowmobile so i will try to get a "dry" weight and "wet" weight to let you guys know how much it is good for.

i paid $140 for it.

 

Five 80# bags of sand cost less than 20 bucks
