Rough dimension for the tub: 29"W x 39"L x 14" Deep
Sides are tapered to allow for cornering. I figure the capacity to be around 7 cubic feet

The idea was to design it to basically carry my camping gear along with a little room for additional things. From my experience if you have more space, you'll pack more things. Keeping it on the lighter side, keeps from taking away from the two-wheel experience.

Normal Contents:
2 sleeping bags
2 chairs
2 blow up mattress
compact tent
rain suits
quick dry towel
2 full size pillows
jet boil for coffee etc.

 

You need some tongue weight with any trailer. But this is exactly why I am using two, with light tongue weight when empty and then I can even haul anything and control how much is on the bike by how I load it, every trip is different. But as long as I can control my gitch weight, as long as I don't overload it, I can keep the hitch weight the same when I find what is ideal every time.
