Some update. Still have the box van. Here’s some of the upgrades or rebuilds over the years. I’ve since designed a bolt on Econoline tube front winch bumper.
For the question about the roof rack, I custom built it and still use it a ton.
It’s been on more trips than time upgrading. The 5.4 has never let us down. We also finally found a 7.3 mini mod Ambo but haven’t done anything to it yet.
