Joey D,
We started this third car seat installed behind the passenger seat. We wanted the seat for our granddaughter so we could put her car seat there. PC installed the third seat in our 2350, but after a short time we decided we did not like the corner bed. So, back to PC about trading for a 2551. But Kermit said not enough room to install the third car seat. So, what is the option? The option was the evolution of the 2552 by extending the coach by one foot just so we could have the third car seat. What other manufacturer would go to this extreme for customer? They also installed the heavy duty "D" rings, we provided, on the floor, front and rear of the seat so you can hook up the tether from the baby seat. There are no latching rings as are on most cars. You have to use the seat belt system on the baby seat and most baby seats provide instructions on how to secure them. With ours, the granddaughter is well secured in her seat and she can watch children videos on the TV with the inverter on. Hope this helps.
