Our TT came with an outside grill that I have been putting inside a large contractor trash bag to store in the TT. I have been looking at shallow and wide plastic containers to store the grill in but could not find a good size. While strolling through the aisles at Lowes I found this tub for mixing concrete. It cost less than $10. What a deal. Hear are some pictures. The grill fits well and goes into the rear storage area with no problems.
not sure if a grill would fit in these, but I have been buying a pile of these for various things. I found them Walmart here in Canada for around $20. Good for camping equipment, tools for work...easy to toss in the truck and go. PlanoŽ XXL Storage Trunk - 27.4gal - Sam's Club
