Thankyou guys. AfterMyNap, thanks for telling me to start a list of questions, thats a good idea. I think my husb wants his dad to have a kinda luxurious looking ramp but his condition is likely just temporary (he will soon use a walker then maybe a cane we think). He is 80 yrs old too.
But he does have to learn how to use it himself (no one to push him) because he lives alone.

Something else...my hubby said he is not going to get a building permit cuz it will "just be in the backyard".
