@ascentale @InkySchwartz @bikenite A7. Trail-a-bikes should be fine. I've been thinking of getting one for the older kid to maybe lighten the load and redistribute the pickup weight a bit. Maybe go the stretchy bike leash thing.
The ones I've seen for cargo look pretty good as well. They work the same way a bike does, effectively, so I think you just lose out on some cargo space for more manouverability. Certainly easier for off-road hauling.
