Just to update-
We did get the Honda Odyssey van with the fold up ramp (as opposed to the in floor ramp). It is working out great; the headroom is fine for my husband who is 6'. (can view on my album-Renovations)
Gramps- yes, the fold up ramp does restrict the use of reclining in the passenger position. This is something I just realize I give up (since I am in the passenger side for now). For those who think this is an issue, maybe look into the ramp that folds into the floor. (at this point, I forget if it is the Summit or the Northstar conversion, on the VMI)
Just look into the pros & cons for each conversion, as it applies to your location/area.
(taking weather into consideration)
What we do- since I am tall & want the passenger seat as far back as possible- before we activate the ramp, I "pop" the backrest forward, and the ramp does not rub against the back of the seat. Then, after my husband enters the van, we close the door and then I return the back rest to a position that just barely touches the ramp.
We realize we are so lucky to have this. and the freedom & mobility it allows us. And, we are glad we made this purchase sooner, rather than later!
Thanks to all for your comments, advise & tips. I hope this will help others when they begin their search!
