Seat problems

Really happy with my truck with the exception of seats. It's been a year now and long drives hauling an rv are downright painful.
Dodge Ram 3500, 4 door, dually
I was under the impression I could buy more comfortable seating and have it installed (or do it myself.)

The truck came with bare bones fabric seats, nothing automatic and hard as a rock. The only adjustability is hand sliding the whole seat and lever adjusting for the actual seat back.

I spoke with a dealership and they said nothing could be done except adding cushions.

I've looked into aftermarket seating but don't understand how all that works, how will I know what is more comfortable than what I have?

Is it possible the truck is just riding too hard (shocks and such?)

My husband has a Dodge Daytona with padded leather seats that have multiple adjustments.

Am I just stuck with my original purchase?

Go to car-parts.com, Put in your area and seats. This site is used by most wrecking yards and you should be able to locate better seats for your 3500.

I have heated and cooled 14 Laramie seats in my 12. They're ok but still kinda hard. Really need to redo them with softer foam

Look for air-hawk truck seat cushions. They are expensive but worth it and way cheaper than replacing the entire seat. I got a pair to use with my '01 and now use them in my '15 on long trips.
