Uh oh. Now you've done it. You asked about my van. You brought this upon yourself!
It is 2wd. I guess calling it "long travel" is relative... it's a pretty mild setup with about 12" of travel all around, but would easily do 14" if I'd bother to move the shock mounts.
Front suspension consists of Camburg bent I-beams, Camburg extended radius arms with uniball pivots, Fox 2.0 reservoir shocks that have been revalved by Agile offroad (I'll be altering the valving slightly soon since they're due for rebuild anyway), coils from Camburg (soon to be switched out with 6" lift Bronco/F150 coils that are ~20-30% stiffer that should net me 5" of actual lift), some Energy Suspension (or maybe Daystar?) polyurethane progressive bumpstops, and limit straps.
Rear suspension has 4" of lift from custom leaf springs that were spec'd by Weldtec Designs (who specializes in vans) and built by Atlas, "long travel" shackles are on their way from Dirt King Fabrication (meant for the last generation of Raptor/F150) to allow the leafs to droop further (stock shackles are currently able to lay flat against the hanger at full droop, new ones are 1.5" longer and boomerang shaped to cure that) and lower the rear ride height ~3/4" in the process. Shocks are just Fox 2.0 IFP's that were also revalved by Agile Offroad.
The rear axle is a full float Dana 60 with 35 spline Dutchman chromoly shafts, Detroit locker, 4.56 gears, and a Spicer ribbed/nodular iron diff cover (I managed to peel the stock cover off in the desert over Thanksgiving, oops!) I'd still like to build a truss over the top of the rear axle to save my bacon in the event of an "oh $4!+" moment, and build bump pads into that (likely just use urethane bumps in the back.)
Tires are 315/70/17 Hankook RT03 muds, I've managed to cut/rip 2 of them in the last 3 months and I can't find anymore replacements (there's a new tread pattern out now) and wheels are 17x9 American Eagle 012's with faux beadlocks (Eagle is now defunct too, so I hope I don't break one!)
Other exterior goodies include RunCool hood louvers which really helped reduce in-cab temperatures when the going gets slow with heavy loads... and I think they look cool. 30" curved LED lightbar in the bottom of the grille, LED projector headlights, amber LED marker lights (all 5, not just the 3 in the grille), Aluminess swing away spare tire carrier with full size spare, Weldtec front bumper, Bully steps (which I'm hoping to replace soon since 2 of them are bent after *somebody* decided it was a good idea to drop an 8,000lb van on them, thinking about giving Nfab's steps a try, and trying NOT to set them on rocks... or MX track tabletops.)
Interior has front swivel seats, an Rtic cooler that lives between the front seats, 2 more bucket seats mounted kinda in between where the 2nd and 3rd row benchs used to reside, and a BoltItOn motorcycle rack directly behind that (can haul 3 fullsize dirtbikes inside.) Yes, it's a 15 passenger van that only seats 4! There's 2 layers of limo tint on all but the front doors and windshield, ~200lbs of Dynamat and various other sound deadening materials, stereo is still in the works (head unit is in but the 2-12"s and 2000w amp haven't gone in yet... I hate running wires)
9 years of ownership and it still does everything I ask of it. Great for roadtrips, days at the beach, hauling dirtbikes, pulling trailers (though it could benefit from more power, it just has a 5.4L) running through the dunes, forest roads, easy "4x4" trails, desert exploring at a spirited pace, etc. and it still gets surprisingly decent fuel economy (16-18 on our last 2000 mile trip NOT towing, 10ish mpg towing at ~16k lbs combined)
We went looking at a new truck a couple weeks ago since I can absolutely justify another heavy (3/4-1 ton) 4x4, but I just don't see the value in dropping 90k on something that we'll use 5k miles a year. We won't be replacing the van anytime soon so I'll likely keep throwing more money at it to help it do what it does... better.
