It seems that making a base storage box that is connected to the top, reinforced and sealed together with fiberglass and epoxy to be one is the way to go then accessed from lift up panels on the inside is the way to go. Placing drawers just above the chassis seems to be a difficult and problematic setup. The truth about this model of teardrop is that it just doesn’t appear to be long enough for the pull out base drawers for stove and cooler. At least not one that intrudes on the leg room for sleeping.
A 4-6 inch base storage could potentially work if built as part of the top.
If anyone has great ideas for sealing drawers then I’d love to know.
