I've had this idea in my head for a while now, i have a Jvc Tp-p205u Heavy Duty wheel Dolly,

after about a month i realized i needed a tracked dolly for using on rough surfaces,instead of

spending thousands on a track dolly i got the thinking and found by splitting a 1inx8ft PVC pipe

down the middle i can push the dolly on grass or any out side surface. hope this helps you

save money and time :D
