Seats in a 2021 Forester Classic w/ Ford 450 chassis

If this is on a Ford, there is an OEM power base that should be available. I have one in my '11 E450 Sunseeker 2300, where my chassis was optioned that way in the Forest River fleet order. A harness jumper to the seat base may also be needed. There are some online parts diagrams available that could be a help.

I agree, the power seat makes the somewhat confining Ford cab much more comfortable.

Just add spacers between the seat base and the floor.

If the only problem is the steering wheel to seat relationship, you can just tilt the wheel down. But if you need the seat to be higher, I would go with the previous suggestion and put in some spacers, either under the base, or between the base and the seat. Even an inch can make a huge difference in the way it feels.

Spacers are certainly a temporary fix. When I was sitting in the seat briefly, I did tilt the wheel down, which got it out of my line of sight. Still though, I felt like I was sitting on the floor!
This morning I was reading through the sales brochure and saw where Forester offer the six way power seat as an option. Why it is not on this rig, I don't know, but it should have been! I am going to see what it cost to have it installed. I live on the east coast of Florida and searching for a Forester dealership, only two came up. and they are not close to me. My search continues! Thanks for your help guys.

One simple, inexpensive, low-tech solution to a too-low seat is to sit on a cushion. When I travel with my dear mother in my motorhome, she does this and it makes a big difference for her comfort. (I assume it would also help with vision when driving, but usually I am doing pretty much all of the driving. That's in no way a reflection on her driving skills, I hasten to add; she's an excellent, safe driver.)

Boat cushion!
On a serious note, I’d bet “most” Cs don’t have power seats. The mfgs buy full lots of the most stripped down cargo chassis to build on.
Sounds like an expensive project if you’re not handy enough to do it yourself.
