It does allow access. Sorry for the dark photos, but in the second photo below you can see the plastic panel that sits above the actual slideout tailgate. That pops right up to access the storage compartment. I have my cargo mat over that panel, which supposedly would no longer fit after this...
I bought it online at Fairway Ford Parts because for me that ended up being the best price with shipping: https://www.fairwayfordparts.net/oem-parts/ford-kit-n2dz99402k19ab
But other online options are Ruxer Ford (talk to @flip who is on the forums), Levittown Ford, or directly from Ford...
Yes, it will slide out if tailgate at 90 degrees and tailgate table down. See pics. And yes, the floor is completely level now when seats folded down. It's glorious.
Installed the slideout tailgate in my Sasquatch OBX (GVWR be damned). Overpriced as it is, I'm super happy with it. One of my favorite additions and I've done a lot. I snagged it for about 25% off somewhere. Probably not worth sticker price but now that it's readily available at a discounted...
Lol. Not sure if you seriously wanted the answer or not but I'll bite. The top side is solid surface, no holes. I suppose you could not put the solid piece in and run it with just the holes, but I wouldn't recommend that. But hypothetically, to answer your question, the holes are a bit...
Just an issue with aftermarket bumpers. I have the ARB rear bumper on mine, which came with a relocation bracket to relocate the license plate to hover behind the spare tire. I'm not a big fan of it. Doesn't look great, and will be really annoying to remove the spare tire now.
I'm no expert but I went with options 1 (JB4), 2 (Roush CAI, if you can really call it that), and 4 (Mishimoto intercooler). Also have a Roush exhaust. I'm very very happy with my build.
Edit to add: if I was going to start with just one, it'd probably be the JB4.
Probably my OCD, but didn't love the gaps it left on the sides. Now, you could get creative and come up with something to make that look better (and people on these forums have, I believe, if you search). Another concern was that the manual says you shouldn't put more than like 50 pounds on...
