If you do find a 1 ton van, check to see what gear ratio it has. The gear ratio is determined by what exactly you are going to use the van for. For example, if your going to be using it more in the mountains and hauling a good load with it, both inside or outside (trailer), then it might be better to go with a 4:10 gear. That is typically what we put in since it pulls well, and also works well on the highway. If you were going to do more highway travel then maybe at 3:73 would work better. So, it just depends on what it's main functions will be. We can also re-gear the rear if you find a van you like but without the gear ratio you would need. We can also install any locker combination that you might need.

Take into consideration what you are planning to use the van for. You want to make sure that it will have the power and durability to run the conversion wherever you want to go.

The process:
What we typically do is figure out which options are going to work best for you. Getting the right parts in and building the axles usually take 2-3 weeks. Once we have all the components built, we bring the van in and keep it for 2-4 weeks depending on the conversion. 

There are a plethora of different options and ways to build any vehicle and we would be happy to put together a custom estimate for you free of charge or commitment!
  So, there is a basic idea of what is involved and what to look for.

 We hope that helps and please feel free to give us a call or email anytime with any questions or concerns!

There are many different things to consider when buying a van to have it converted to 4x4. 

Most of the vans we convert are 3/4 or 1 ton
  Chevy 2500 HD, 3500 (8 lug) or Ford E250, E350

We do convert the 1/2 as well, although it is more expensive and time consuming. 

Slider door vs. Barn doors:
One important thing is that it has SIDE BARN DOORS! The vans with the slider door will not open all the way with the lift and larger tires mounted. However, if it a special independant conversion we may be able to get by with the slider, but it truly depends on the build.
With that said, those are really the only things that can make a big difference when building this type of van. 
Keep in mind that we have the ability to build virtually any vehicle however you desire!
There are always lots of options!
