Question Frontier question...

We are thinking ahead to when baby comes, we will be putting DD3 in the bench seat in the back when baby is born...problem is I cannot find a seat that works with our long buckles...the MA fit but it expired this month, we have a GN installed right now just to try out and I have the buckle twisted 3 times and it seems tight but after riding in it once or twice,it will loosen up, it makes me nervous to have that be her long term seat. Right now she rides in a RN in the middle row captains chair and I love it but I cannot get it to install back there at all..

I was wondering if the LBP on the Frontier helps at all with long buckles, she will be 5 by then and is 38lbs. right now, so probably somewhere around 40lbs. by then, and obviously we can do a booster for her by then, but I feel more comfortable with a harness until at least 6 and with her going all the way to the back I will not be able to see how she's doing in the booster...so anyone with experience with longer buckles? What seats have worked for you?

We were also contemplating a TFP that she could use while baby is in the bucket and by the time baby would need it she would be ready for a booster, I know it has lockoffs, I didn't know if that would help with the loosening...

BTW this would be in the rear bench of a 92 T&C with no headrests in rear bench.

I found the Long Belt Path helps with long buckles so long as it is not just a lap belt.
