I am in the Seattle area and would love to see one of these as well. Looks like it solves a lot of problems for me.

I've had mine since last fall, and it has been fantastic! We do a lot of camping, and it is great to have an enclosed bed to carry all the stuff we bring along. I got the tool box option on one side, and that makes for a really convenient place for my tools and set up supplies!
Assembly is a bit tricky - like an IKEA kit, but with sketchy instructions. I was able to assemble and mount by myself (with a tractor to lift onto the bed) in about 4 hours.

Finally got around to designing some mounting brackets to utilize the Mars Accessory Adapters to mount the topper and get them fabricated. Absolutely rock solid. A bit tricky to install with the storage boxes since you can't easily see the adapters to align the bolts, but with enough patience I got all four brackets mounted. If anyone is interested, I can order more and have them shipped directly to you. Just let me know. Price would be dependent on exact material thickness and finish.

The mounting brackets look great. Will it work with the Weistec adapters? How much?

Looks great! I’d like to order a set. If you’re happy with yours I’d just copy the same setup.

I don't have the Weistec adapters myself, but I think the answer is no. Weistec list that they use M10 bolts, whereas the Mars adapters use M8. Weistec doesn't list their center to center bolt spacing either.

The mounting plates I made are about $135 total for four plates as is (0.250" thick with texture black powder coat finish). Going with a thinner material and/or omitting the powder coating can reduce price. Final price is dependent on exact taxes and shipping.

Thank you for getting back to me. I will need to consider and determine if I should go your route. Thanks again.

Forgive me if I've missed it in the thread somewhere but can someone give me the dimension in the photo i.e., the outside distance between the luggage rails? Thanks!

Still really interested in seeing one anywhere in the Seattle area if anyone has one.

Anyone made a walkthrough video of this cab? I‘m interested in ordering this. Probably missed my chance for the current batch?

I received and installed the cap this past weekend on my 23 T. Placed the order in March.

Overall, an excellent value and product. The box was delivered via a local carrier and was very beat up. I was concerned about damage, but after opening, all of the parts were nicely wrapped. A few things needed to be bent into position, but nothing major.

This took a few hours to put together and the instructions are useless. It was pretty easy as there are only a few pieces, but took a while to bolt them together. We sealed all of the inside and outside seams right away. The sealant is a black rubber compound. Wear gloves. Plenty of hardware, but not enough bolts were provided. A quick trip to ACE was the fix.

I did a 70 mile highway test drive. No rattling or extra noise. I did not notice a range hit at all - in fact it appeared a bit better. We are planning on going camping and mounting an RRT on it. Will report back after.
