Would love for this to be long enough for me
Here are the racks I have: https://vantech.us/product/h1-diy-ra...nversion-vans/
See the photos below. My top is approx. 19" high and cross bars sit about 2" above the top. I did this so I could get a wash cloth or brush under when cleaning the van. I could have went a little lower but it works. The top bolt of the cross bar mounts are drilled about 5" below the top of the vertical support so technically you could get another four inches higher. However, the website recommend to only go as high as 23.5", so you'd be a 1/2" higher than that. Likely ok if you aren't planning to carry heavy loads. You could add a third cross bar where you'd typically have two if you wanted to beef it up.
This one shows the height of the platform down to the drip rail. Tough to see in the photo but it measured about 23.5"
This photos shows the height the cross bars are drilled into the vertical supports, top of the support is about 5" from the top.
Note that I purchased the aluminum version which has a longitudinal stiffener that runs the vertical length of the support inside the tube. You have to drill straight this "rib" to attached the bottom bolts of cross bar support. I tried but the drill bit kept drifting out to the edge. I had to take the four vertical supports to a machine shop and have the holes milled out. It cost me about $40 to have that done, more a nuisance than anything. The top bolt drilled through the side of the rib so that's easy was easy enough to do myself.
Also setting the height of each cross bar was a pain since the drip rail isn't level across the length of the van. I must have measured 1000 times but only drilled once and got it dead nuts.
For what it's worth, my rack feel quite adequate and burly. I feel like I could have four or five people up there and not be worried about the weight.
Good luck with it, let me know what other questions come up.
