Seat E450 Ford

I used a 1 1/2 inch square tube. Drilled appropriate holes and put it between the seat and the mount. Works great, gives both me and my wife the elevation to see out nicely and she can still reach the peddles. I also took the opportunity to move the seat back about 1 1/2 inches as I wanted a little more leg room and it makes it easier to get from the drivers seat to the rear of the motorhome while still having enough forward movement so that wife can reach the peddles.

My E450 chassis Sunseeker came through from Forest River with an OEM option 6-way power base. Might be an option on the unit being considered.

I use a chair cushion and it works out fine.

Easiest way to check first, is to follow DrewE's advice & find a cushion roughly 4" thick.

Maybe you need to look at a used Class A with electric adjust capt chairs. Dick

Never thought of the possibility that I could not reach the pedals. I didn't check to see if there was enough space.

Good solutions from all. I will have to go back to the motorhome and see if I can actually lift the seat and still reach the pedals.

Thanks to all who replied.

4" is quite a bit of lift.

One simple, low-cost solution (at least a partial solution) is to sit on a cushion.

Raising your seat 4" will effectively shorten your legs 4". This might not be what you want unless you are tall.

I needed the extra height for leg room and took our unit to a local fabricator
who fabricated a 4" riser that is bolted between the floor pedestal and the plate that has the seat mounted to it.
only downside is that I now look through the blue tint stripe on top of the windshield when I am driving.

Four pieces of 4" steel tubing about 6" long. Drill holes on opposite sides of the tube. Unbolt seat, bolt tube to floor and bolt seat to tube with class 8 bolts
