I'm sure they will fit, but not a lot extra room for two dogs to be comfortable. Depends on how each dog tolerates the other in close quarters. Good luck either way!
I just removed the seat bottoms. I used a semi soft back seat platform, and a "backseat dog hammock". I think I purchased both from amazon, I don't remember, they were purchased 7 years ago. Both were used in the F-150 that I traded in on the new Ranger. My dog has enough room to turn around...
