After much hunting I finally got a Burley kid trailer on Craig's List for cheap! It was already gutted for cargo use, but I want to mod it further.
Sellers pictures from CL:
I stripped it further by removing the top structure and the bottom, the bottom was made of fabric:
I'd like to install some kind of crate, basket, container, here are the inside dimensions:
This is for light duty, I figure the heaviest I may carry is some groceries 30-40 lbs would be absolute max. So I don't need hardwood platform or anything like that. The frame is rated for much more I believe, 90lbs or so - two kids. I'll use it mainly for large but light things like a pack of paper towels,bag of laundry, set of wheels, a bike frame, etc. I have no need to carry concrete, pet food, soil, sand, etc.
I like an idea of a large, flat crate that would be inserted inside the main square, lowered to keep the center of gravity low. It could be simply attached with several zip ties and I'd be able to use a bungee cargo net to keep things in place.
The problem is I can't find anything this size. Any suggestions? Two crates would work too. I can also add aluminum cross-bars underneath if needed for support.
Or I could just use a Rubbermaid storage container, they come close in size to what I need. Some of them are waterproof, that's an advantage, but they're too large for my liking. If they were the same width and length but half as tall, they'd be perfect.
I'll go tomorrow to Target, Walmart and Home Depot, see what they have too.
