Here's a suggestion for adding tie-downs to the Croozer. Find a rubbermaid storage tote that fits nicely inside. Drill several holes around the the tote about 2 inches from the top. Attach rope loops through each hole and make a big knot on each side hole to secure. This gives you places to hook on to. I've been using polypropelene rope loops to tie down some big loads and it seems indestructable. The tote might even increase the weight limit of the Croozer.
