Hi and welcome to the forums at Car-Seat.org.
What kind of vehicle are you driving? Chances are someone here has either seen one or owned one, so that would help with making suggestions.
The Eddie Bauer 3in1 seats do tend to take up a lot of room rf'ing when installed at a newborn recline, but when installed more upright for an older child, they're not too bad. Based on the year of manufacture, your base is removeable which would also give a couple inches more in the front seat.
Otherwise, the True Fit, My Ride, and the new Britax seats are all pretty compact in terms of front to back space when installed at a more upright angle. And at 10 months your kiddo doesn't need a newborn recline. The complete air is also decent when it's installed more upright - I had it rf'ing in my Saturn Astra and my over 6' tall dh was still able to ride in the passenger seat.
The Evenflo Triumph is good in terms of front to back space, but it only has a 30lb rf'ing limit and unless a child is very petite, I generally don't consider it as an option. The longer a child is rf'ing the more protected they are, and I really like to see kids get at least over age 2 provided the child fits the seat still. Unfortunately that 30lb rf'ing weight limit isn't enough for a lot of kids so I tend to not suggest it very often now that higher weight limit seats are so easy to find.
