Thanks for all the input guys! I just dropped my Van off at Ford. They will have it for several days to investigate the leak. I had them check my warranty and I lucked out because it expires this coming July. I'll keep you guys updated on the findings. I do not have any roof rails on my van and everything on the roof is completely stock. When I bought it, it had 10k miles on it so I'm not sure if the windshield had been previously replaced or not. Hopefully its nothing major!
It sounds to me like you're planning a camper-van setup? Offhand, I can tell you the LWB van is around 7ft from the back doors to the front seats at floor level, so I'd give a rough guess of 4.5-5ft to the back edge of the folded second row seat. I have a cargo van instead of passenger wagon, so I can't measure the exact setup you're asking about, but a LWB is a LWB either way.
ETA: That applies to TC2 (2014+) vans because mine is a 2015.
My town has only two paved roads, everything else is gravel - so, needless to say, my wash routine is very lazy, haha. I pretty much just rinse off the dust about 6-8 times a year (usually no soap, even, except maybe 3-4 times a year), not counting any rain that might happen to occasionally rinse the van a bit. I could (and have) fully clean it in my yard, go back out an hour later and it's dusty again just because somebody drove by. Talk about just spinning your wheels, going nowhere fast! lol. But, I wouldn't trade a minute of the country to be back in the stupid big city.
Doesn't make much difference with the 3rd row in or out the width and length are the same. I'll look into it in the morning and let you know. I do no a 4x8 sheet of plywood will not fit. The only reason I take the 3rd row seats out is it gives a bit more headroom for hauling stuff like my scooter. Its an amazing van but which has an incredible amount of interior space considering the outside dimensions but it is still a small van.
Bearings are more standard than most folks realize. There is probably a number stamped on the side of the race or bearing. You should be able to cross reference that number and find one that is the same size and capacity. If my memory is correct all bearings are actually metric sizes and have been for a long time. Cross reference using Dr. Google the bearing expert.
Usually I just go to a replacement part but on a couple of rare occasions Ive actually used the bearing numbers.
Hope this helps.
