Vans ...
We own the Chrysler mini van and like it enough for daily travel. The van has side entry and it also has a feature called kneeling which means the rear of the vehicle squats down so the travel up the ramp is minimal. I used to love to travel and get out and do everything I could. Something to consider before you spend $50,000. on a vehicle, just how much will you use it and once you can no longer talk,walk,eat and use your arms, will you really want to go out. After 5 years of this damn disease I find it to be quite a challenge for myself as well as the hell my poor wife must endure helping me in and out,locking down the chair and everything that goes along with it. If I had endless $$$ coming in I would have definitely purchased a full three quarter ton van with the side lift , not a ramp and get the automatic locking system. They only come with lowered floors because of the codes they are forced to adhere to. If you are patient you may get fortunate enough to find a used van for a good price. I got mine for $20,000. in excellent condition and only 11,000. miles on it. We found it through the ALS community.
Now wheelchairs are quite involved and depending on how you get along with your doctor he can write a script that will have medicare paying for the maximum. Tilt in space, chin control and leg lifts .I have both the Invacare TDX and a Permobil. I would chose the Permobil over any chair out there hands down. If you ask the pros. which chair is the top of I'll bet Permobil comes out as number one 9 out of 10 times. That's not to say the Invacare is junk it's just like comparing a BMW to a Cadillac.
I spend more time having work done to upkeep the Invacare and no maintainance on my Permobil. The best thing for you to do is try them out. I think you will find your doctor will be your biggest alli when it comes to all of the utilities you will eventually need.
