Yea a 10 foot Kayak will fit inside the Ascent.
Wow hope you weren't in the front seat. I'll just carry it over to the swim ladder here. I had a Thule rig for the Outback, I put it on once to see how to install it but then never really used it.
I've certainly put a few sticks like that in my Ascent, but if I need more than a couple of something, I use my trailer. Today was an example of that for the project du jour...I've brought home 10' 2x10's inside the car when guys that use 4 door cars with open trunks pull a trailer. I mean, why get a truck if you can't carry stuff and need a trailer. For stuff like that a car can pull a trailer as well or get a bigger SUV...
