I have had this issue on my 2005 Bigfoot 9.6e 2500, I believe it's basically the same camper as yours except yours is dry bath with a longer rear overhang. I posted approx. a year ago in your thread about your warping, cracking plastic bottom inspection plate, That warping inspection plate is your issue. Bigfoot cut out large parts of it's structure and then installed a flimsy plastic cover. When the camper is on the jack's that section of camper, what used to be the bottom of the camper, goes under tension forces, then when you put the camper on your truck it goes to compression forces, and you get a pucker or warping of your thin plastic inspection plate. I did a great deal to fix this but bottom line is you need to replace that section of floor that bigfoot removed and make it a structure again. Simply put I removed the flimsy plastic and installed 5/8" plywood across the bottom of the camper.
This my sound a little strange but I highly recommend you make a cardboard model of your camper rear wings of the camper and everything, just use duck tape or hot glue gun to hold it all together, cut out the sections of the bottom that Bigfoot cut out. This will show you how flimsy the rear wings and overhang are, then with glue or tape reinstall the bottom that was cut out. You will quickly understand what's going on structurally with your camper.
Arm yourself with a little knowledge, and your cardboard model of your camper and the dealers will find it difficult to take advantage of you. Find someone that will listen to you, if they don't move on.
