The travel van that I had was 1991 f---d E- 150
the inside was done by a company called Jayco...it was one
of thoes vans that you could sleep in...This is where I got
my rear seat for my 46 panel..It can be used as a seat or
turned down into a bed..it was held to the floor by four
clamps..which can be removed...I measured the inside of the
panel and then I cut the frame to fit inside the rear wheel
humps...53"..I have it now at the shop to be recovered to
match my new front seats which I bought at summit..There are
low back seats..I also used the mechanic's of the middle seats
from old van they tilted forward and installed them in the
panel. Now my new seat on the pass. side tilts forward..so
riders can get into the back and also I can get a my battery
box..Hope this explains what I did..
