My own take on the wood cart. 39$ Dolly from Canadian Tire. 2 - (2x3) Top Bottom Plate 2 - Strapping 8ft 2.5" screws and 1 1/4" screws. Cut 2x3 into 4 - 18" and 5 - 10.5" Assemble top and bottom. Bottom outter's are inset 1.5" and an extra middle piece. 2.5" screws Top is simple square frame. Cut strapping to 4 - 4' pieces. (you will need an extra 18" piece of strapping) Inset the strapping that will sit inside the dolly's frame rail. attach with 1.25" screws to boxes. Front are a bit farther apart. Then take the 18" strapping and sandwich the frame rail to the upper box. 2.5" screws. You are welcome internet. :D You could take your time and if you have the room, encase in pallet wood and stain. It's funny. At first I was all about appearance. Wood in a copper tub. Cutesy. Now it's all about the least amount of effort and the most amount of wood I can get into the house in 1 trip. The house can be nice looking in the summer.
