Hi steffen707,@JAY, IT ISN'T BEDTIME YET!
You stated in the most recent, news flash, https://www.jeepgladiatorforum.com/plywood-question-put-to-bed-yes-they-fit-flat-in-the-gladiator/ that "P.S. in case you didn’t know — setting the Gladiator’s three-position tailgate on the middle setting matches the top of the tailgate up with the tops of the rear wheel housing and enables the Gladiator to carry 20 sheets of 4×8 plywood or drywall flat; this is according to Jeep."
Well the JT manual says we can only put 300lbs weight on the tailgate at half position. So we still have a possible bed problem!
Even 1/4" plywood weighs about 22 lbs per sheet, at 19 sheets that's, 418lbs......hey @JeepCares , which is it, 418lbs or 300lbs? Is Engineering right, or is Marketing right? Or did Marketing not take the engineer's numbers correctly?
i'll post the manual in a sec. https://www.jeepgladiatorforum.com/forum/threads/gladiator-owners-manual-download-in-pdf.15679/
We have checked with our internal resources and after conducting additional testing, Jeep engineering has confirmed that up to 500 lbs payload can be carried in the bed with the tailgate in the mid position. This payload rating is dependent on the sheet cargo being properly supported with 2x4s positioned in the bed as specified by the owner's manual. Future printings of the owner's manual will show the new 500 lbs payload. I hope this offers some clarification!
