Does a car seat fit in a 1st gen Access Cab (Asking for a friend)

Yes, middle seat like you have yours

 

Those are ultimately CYOA (cover your own ass) numbers from Grayco. The reality is, as long as you have more than 60% contact, it's not moving.

This is also what we used, and that style of click-in is a lifesaver. But I think we used the Chicco brand, and the base was pretty compact overall.

 

We discussed this style but aren't they only used for infants and grow out of them quickly? These things aren't cheap. The Grayco car seat we bought has gone up $60 this year because of tariffs. Most car seats are made in China.

We didn't want to have to buy new car seats after a few months which is why we went through convertible route.

 

I'm pretty sure we used the same seat for at least the first 12 months, I don't remember upgrading a ton. Our doc told us everything on when to think about upgrading, dunno if stuff changed since. By the time we were ready to upgrade, 2nd baby was 3mos on the way; sadly lost that kid a few days after the 4mo mark, but got lucky 3mos later, so ultimately kept the bases and refreshed the fabrics on the seat.

But the reason we liked the snap-in base system that Chicco used is simple:

• We have two cars, we bought an extra base and installed one in both cars.
• They had a ton of options, like a bassinet you could snap in, and the basinet was also able to snap-in to a stroller frame, very convenient.
• Snapping the kid in and out was a breeze, just tilt and push to click them in, press a button and pull up to pop them out, no stuggling with straps and other bullshit.

I would be shocked if someone didn't have size-uppable seats that work with the same base as the kids grow at this point.

It's better if you stick with one system though, and think bigger picture. Honestly, this may sound stupid, but we went to a local baby store. Those MFers know everyfuckingthing there is to know, and what products are on the market. If you drive there with your 1GT, you may even be able to set the seat bases in, and test fitment if the people at the store are cool like that. The place we went to was called New Baby Products, on Cheshire Bridge here in Atlanta. I don't think it's a chain, but may give you an idea of what to look for locally (Looks like someone built apartments where their building was)

 

I have a 360 seat in mine. The baby has been in the truck once, but next week I start dropping off at daycare.

I will say the 360 is nice considering I don’t normally worry about strollers and whatnot.

 

Yes they grow out of it, but we used it for the first year plus. Everything @shifty` listed as reasons for that type of infant seat are the same for me.
I get that all this stuff is expensive. I know this isn’t necessarily “kosher” but check thrift shops or hit up any people you know with young kids that may be getting rid of an infant car seat. Just google the serial number to check for recalls before putting the kiddo in it.
