My new ambulance, starting the conversion

Thanks guys, yeah were trying to get it done. The wife is taking it to Arkansas april 1st (unfortunately in 2wd only LOL) so we at least needed the interior and wiring done but she couldnt stand the paint so we squeezed that in there too.

More of an update. Here is the control panel, it allows us to run the left, right and rear flood lights, interior lights and several other things. The radio obviously runs the tunes and when turned to aux it will allow the tv to run through the speakers.



Overall shot of the interior. We made up the cushions ourselves with parts from the local automotive upholstry shop. The fridge is pretty large and from lowes, we did consider a 12v/110v fridge but at around $1K we couldnt justify it since most places we will be going we can either run the truck (mostly on long road trips like to alaska or colorado), run the generator or be plugged in so for a cost of $300 it does everything we could want. I'm sure alot of people will argue that these fridges arent made for off road or even on road use but alot of RV folks have been using these things these days and have great luck out of them. If we were boondocking for days on end we would have went 12v but were just not planning that. You can also see the bed pieces over to the right (the grey things down in the cubby hole)



Just a roof shot, coleman a/c unit, etc. We replaced the center wiring cover with some 1/4" carpet covered board.



Here is how we make the bed. We simply pull these inserts out of the cubby hole next to the fridge pop out the 2 legs (cut up table legs rated at 1000# each) and put them down, the whole setup takes 15 seconds. Its about the size of a queen size matress so it easily fits our family.



We just need to finish 2 pieces of trim by the roof and some cleaning up.

Finally finished the van after being gone for a month. We installed the 3" spacers on the rear axle this morning (had to change a few wheel studs as well since they were damaged from the previous owner).

We installed a new 4r100 with several upgrades instead of the 6spd I wanted to do, it was almost a direct swap (changed the internal shift arm to use the E4OD neutral safety switch) and it shifts nice and smooth.

To clear the borg warner 4407 transfer case we used we had to remove the catalytic covnerter as a side affect of doing that the engine is about half as noisy as it was before.

I do still have a few things to fix like adding the rear air bags to help with side to side sway, replace the front rotors (I turned the stockers down but I think they are still warped a bit). I also have lost all my rear tail lights for some reason except the right turn signal, odd.

Wow that's looking great, I had big plans to do the same with my ambulance but decided to sell it. Someone in Ohio bought it and drove it all the way back there (from WA). Very nice built. Now you make me wish I still had it.

Note the stated GVWR is based on the OEM suspension. The axle, suspension, tire, chassis combo you end up with alter this. I.E.- any upgrades in carrying capacity/stiffening you make will likely increase the theoretical GVWR. The axle is likely your limiting factor.

Suspension is probably the last thing limiting GVWR

90+% of the rigs on the road are limited by one thing.

OEM spec'd wheels/tires.

Next up is the axles.

The manufacturer doesnt care if you have the suspension bottomed out, riding on the bump stops. Just so long as you are not overloading the tires or axles, you are gravy.

Im not familiar with the Nittos hes got, but Id venture to guess they have a payload rating of 3000lbs each or so.

The rear axle should be (sorry, didnt catch a confirmation which one it is in the thread) something along the lines of a Sterling 10.25, which has a payload rating 7000lbs or so in SRW (single rear wheel) form.

The solid axle D60 has a payload rating of 4500 lbs or so.

So, 4 tires @ 3k = 12k lbs
Front and rear axles = 11,500


Please adjust those figures if Im totally off base. :)

IIRC on pirate he posted that the rims were 3600# a piece and the tires were 4080# a piece.

rims should be good for 14,400# and the tires 16,320#

my 2010 dodge d60 is now rated for 5500# up from 5k on the older ones. I do not know what the 03 ford d60 is rated for though.

Thanks guys, it was alot of work but its turned out great. I'm back in north dakota working again but should be back home at the end of the month to finish the tail light wiring and other minor things.

I went with the 18" nittos due to their high weight rating of 4080lbs @ 80psi. I feel that the ambulance has a much higher than stock weight rating and definately more than I will be needing since we will probably not even be hitting the stock limit.

The springs Chris spec'd are spot on and give a better ride than stock as well as making the rear sit about 1/2"-3/4" higher than the front so it doesn't have the popular (and ugly)new dog dragging its tail look. I'm not sure if this was on purpose or not but I did weigh the van before we ordered springs and I added a bit of capacity so we can tow our 21ft bass boat sometimes.


I bought a 2004 10.25 sterling rear axle to match the front dana 60 but it turns out the original ambulance dana 70 was wider allowing me to use thinner spacers. We wanted the rear tires to come out to the edge of the box but stick in a bit to get that the sterling would have needed 5.5" thick spacers to make the tires stick 1" inside the rear wheel wells. With the Dana 70 we used 3" spacers from Chris to make the tires stick 1" inside the box.

Total height overall from flat ground to the highest point of the rooftop a/c is 9'10" in case anyone is curious.
