There are several things you can do:
- portable ramp to push the empty wheelchair into the van
- lowered floor minivan with a ramp
- full size van with a lift
For minivans, if the person is going to drive /be pushed into the van in their wheelchair, you will need a lowered floor van with a ramp. You can't add those to a minivan later; they are huge modifications.
If you have a full sized van, you can add a lift later, but would need to plan before so that you buy a van that can accomodate the lift.
There are several major brands that are the major 'players' in wheelchair accessible vans. Those companies buy vans from the major auto companies and then modify them to be accessible vans. They all have local dealers in various parts of the US and many are members of NMEDA that was mentioned by a previous poster.
All the US automakers have mobility programs which will give rebates for accessibility equipment. Exactly how much money depend on what modifications were made.
Braun makes the Entervan and also a rear entry van. We are on our 3rd Entervan, side entry van and like it very much. We had also looked at rear entry vans - which does solve the problem of needing space on the side to lower the ramp. For us, it just was not a good 'fit' - there was not enough storage space in the back.
Braun also makes lifts that can be added to a full size van.
Rollx is another big player.
VMI is the other big company I am aware of.
I would suggest looking at those websites - they have pretty good pictures and some even have videos. Then, look for dealers for the ones that look most interesting to you. You will find that most of the companies use Chrysler and Dodge vans . One reason is the size and another is that those vans already have power doors for the rear doors.
There are a couple of big companies for the tiedowns - for ones you hook up yourself,
Q'Straint is one of the most popular.
There are also automatic tiedown systems, like the
EZLock system that was mentioned. We had one of those when DD had a power wheelchair that did not have built in spots to secure the tiedown straps. When she got a new wheelchair with built in spots, we did not use the EZLock anymore and did not get it on our new van. FOr us, we are happier without it, but for some people, it is a necessity - like someone who is driving their van from a wheelchair and would not be able to attach the tiedown straps.
