New gears are installed. I also added a Detroit True Trac limited slip in the rear. The truck can go 60mph at ~2800 RPM, which is great. The downside is the 2.4 liter NA diesel runs out of power going up hills, and requires a downshift to 4th gear. 4th gear feels just like 5th did pre-gear...

I think so. It's an interesting idea, but my truck is at the shop getting new gears. I know a few folks that have these trucks and most are interested in regearing them. I'll pass the idea along.

Is that an Astro? Whatever it is, it's a good looking ride.

A few folks seem to pop up on the JDM posts just to let us enthusiasts know that the vans suck. It's cool if someone chooses something you didn't choose for yourself. That doesn't make your decision bad. It's just different. We have different motivations. I'm not wrong because I didn't agree...

I have a "real" 4x4 hiace. I got the Hiace for two reasons. It is basically new, with 12,000 ish miles on it, and it's cool. If it had 100,000 miles I probably wouldn't have bought it. You can get some parts at Reilly's since they are fundamentally 2nd gen 4 runners on the bottom. Some of the...

I have, but it depends on what you mean by "long". 3+ hours over hill and dale to get from Portland, OR to Seattle, WA, multiple trips to Snoqualmie pass in the cascades at 3,000 feet, 1.5 hours away, trips around a hilly city. I agree that regearing isn't necessary. Nothing in this forum is...

Cut and built. Could be tighter, but it doesn't flap much on the highway. just as you said, a top like this can be designed and built to disregard the frame. That's not how I built mine.

My truck has a 2L (2.4 liter) diesel. It wasn't common in the US. The manual says redline is 4200 rpm, online resources say it's 4800. Peak HP is 3200 rpm (85bhp), peak torque at 2800rpm (120ft-lbs). It's all a bit slower and lower than the 22re. It feels like 3,000 rpm is fine for mid-term...

My truck came with 5.13 gearing in the diffs. Combine this with a 4200 rpm redline and well... it's a slow truck that has a top speed of 62 mph at almost 3500 rpm. 30mph also sits at a weird spot in the gears, just between 3rd and 4th. it makes city driving a bit irritating. I've been looking...

this does require slightly different analysis methods when designing the structure, especially for fatigue, which will be critical for this application.

There is a lot of colloquial knowledge when it comes to materials. Welding a heat-treated material doesn't ruin it. At most, it returns it to an annealed state, but even that is unlikely since the annealing process for aluminum requires holding the material at a critical temperature for hours...

Thanks. I'm definitely going for functional, not luxurious. I've been carrying the bikes on the outside of my subaru for years. I think they will be ok. I will probably get a cover for them when I'm out in the truck. I was planning to add 1" xps on the inside, I can route channels in the XPS...

There are no good recovery points on the frame. I think the end was simply lopped off to add the step bumper. I'm currently fabbing a simple beefy bumper with receiver and it will connect with the frame extension to add recovery points in line with the frame. Bikes are "Light", but my Mountain...

Hope to use it to mount the camper. I also want strong recovery points and a solid base to mount a bike rack back there. Sent from my iPhone using Tapatalk

I'm planning a custom build from the frame up, not a slide-in. Not sure how I will mount the box to the frame, as I still need to test frame twist.

Made some progress welding up the bumper. I know the welds are ugly. It's been a while since I did any welding. I'm a pretty good grinder. It's all 10g mild steel, mic'ed to about .132" thick. The receiver was pre-heated to ensure good penetration from the welds. There will be some recovery...

Here are a couple of ads I found in the Seattle Area, where these vans are pretty popular and have good support from local mechanics. FYI - Craigslist is a fairly popular person-to-person ad site for selling... anything. There are other places to look like OfferUp and Facebook marketplace...

Thanks for the input. I mean, in generalities, sure. The frame of the base truck is fully boxed. It's beefier than almost any domestic I've seen. From my research, it's a Land Cruiser 7x series frame with a DOKA van cab on top. I'm pretty sure it's rated 1.25 tons, even though it's smaller than...

Thanks for the reply. Yeah, the angle isn't doing squat. It's a leftover from the firetruck step bumper. They welded the ******** out of it, all around the periphery, looks like a fat arc weld. I'm trying to not disturb the weld since it is so intrusive. Lots of cutting/grinding/patching. A sleeve...

I've got an old Japanese firetruck with a step bumper on the back. There is a bunch of junk welded to the frame to support the bumper and I want to clean it up and add a more "normal" bumper. additionally, the frame box section is an odd size, probably metric. I also need to extend the...
