[QUAD-L] help getting wheelchair into van

[patricia keen]

I just bought a Ford Windstar minivan to be able to take my brother 
on outings.  He weighs a 175 lbs, and his chair probably weighs a 
good 50 pounds.  We bought a 7 foot wheelchair rampfor $300, but it 
is still next to impossible for me to push him up the ramp by myself. 
Are there any low cost options that would help me pull the chair.
Thanks.
