Looks good!
You could have the tires chloride filled like they do for tractor tires. It would be heavier but not sure by how much.I had to add weight to get it to pack right. Could also prob fill the tires with windshield wiper fluid at about a gallon per tire. 1 gal. = 8 lbs x 13 =104 lbs
Looks ideal for my needs, I gotta' build one. What size is that pipe?This is the one I built last year...works well for my needs
