1981 Toyota Helux Trekker

My dad passed away last year and left me with this vehicle. I belive it is a 1981 Toyota Heliux Trekker. I know he never wanted to get rid of it because there was something special about it. It is in bad shape though. Rusty, hasn't ran in 20 years, not sure why, interior needs gutted. My question is would anyone be interested in buying thus or is it a lost cause?

So it may not be a Heliux, but it is the Winnebago one.
