Justin,post your location and the distance you are willing to drive to get your measurement and ask for a volunteer.You are welcome to stop by and measure my TC. Also,join the Transit Connect Camper facebook group.You may find someone in the middle of a build who is willing to measure.

jdub3 Yes,I believe so.(no label but measurements seem to match)

Don't know if this will help but here's a picture of my 2016 with an older yakima box. There is room to slide the box over towards the edge even more but I like to access it from the rear sometimes

Some thought should be given to placement.I know centering looks the best,but if you ever plan on purchasing a roof box like Thule or Yakima ( I have one and they're great),you will need to offset the location.

Just guessing you have right hand drive? I went out and looked at my 2016 and when I tried to pull hood latch with the door closed,the latch handle would hit the plastic door panel before the hood would pop. However,if i grabbed the handle on the side closest to the exterior,I could gently pull it diagonally enough to clear the plastic panel. Some booster packs will charge your battery through your cigarette lighter. https://mechanics.stackexchange.com/questions/15893/is-it-possible-to-charge-car-battery-through-cigar-lighter-socket

Door won't open or won't unlock?

I would try and contact seller.He has a pretty good rep and has been mentioned in a few conversions as a seller of thinsulate insulation.

You don't say what you want to install.There are some threaded holes on the side walls that I assume are mounting points for seat belts in the passenger version.I have installed D rings for load restraint in my 2016. There are also metal ribs where you could use self drilling screws for lower strength attachments.Your ply lining is attached to something.It may be best to remove plywood and inspect,depending on what your needs are.

Silicone caulk. If you change your mind it would be easy to remove. If you don't care if it's flat,use hex head metric bolts.

Do you have a number or picture?

My wife says she "hates" my 2016 LWB because the passenger seat is so uncomfortable.We both have had hip issues,she has had a hip replacement and I have had a metal rod inserted through my hip joint to repair a broken femur. We called this type of seat a " bucket seat " in the 60's.The raised sides would keep your butt from sliding around as you made fast corners in your Mustang or MG,something that's not really needed in a TC. On longer trips,the TC seat becomes uncomfortable because you are forced to sit in one position with the seat sides applying pressure on the hips.(neither of us is exceptionally wide). I have purchased memory foam bathmats from a big box store which,when folded in half,adds about 2 in (uncompressed) to the center of the seat which does help,but does not solve,the problem.

When I used to haul my sail boards,I would use 2 straps for each board on the cross bars if side by side or use 2 straps on stacked boards with a foam "wishbone" in between.You also need a stiff foam covering(think pipe insulation) on the cross bars. When strapping to roof rack systems,you want most of the force downward ,not outward,to eliminate any side to side movement.

I would go to a glass shop and get a piece of glass installed. I had that done on my 2016 last year for about $100 and it made backing out of driveways and parking spots much less challenging.

You may find the vinyl not stiff enough to overcome the soft carpet and the corners of your storage boxes will dig in.Vinyl can get"sticky" when hot. You may need a piece of 1/2 or 3/8 plywood in between. A thicker piece of plywood would also give you a secure base to build your platform. I used just plywood over my cargo mat and cut 3/4x3/8x4 ft "slides" from some scrap Trex to mount on the bottom of the boxes.They slide so well that I had to mount latches to keep them closed when I accelerate.
