Being a truck person most of my life, I was more than pleased to find the following after being wheelchair bound eighteen years ago (poor me)
.
I just purchased a 2004 Titan King-cab SE with a few thousand on the odometer. It was converted into a wheelchair driver accessible truck. The mods include a drop floor (approx. 6"), lower door ext., remote drivers side doors, an under vehicle lift, hand controls, 2.5" level front w/4" overall body lift, full side length body flares and dual exhaust. It is currently the only one in the world, but with this trucks ease of conversion without major frame mods, its popularity will be growing.
I should have my new rims shortly and that should complete my truck. That is, until the stereo mods.
