hello to everyone. I have a question that I am looking for some suggestions on. My family and I are going on vacation in a couple of weeks and my wife and I are getting a little concerned that we are not going to have enough room in the van to take what we need. We have a 2005 Pontiac montana sv6. All of the seats are pretty much taking up from me my wife and our 3 children in which 2 of them are teenagers. We have the cargo holders on top of the van but no slats. would anyone suggest putting anything up there if I got slats and strapping down real good? If so where would I get those slats from? I wouldn't be putting much up there except for some fishing poles and a couple sets of golf clubs. How durable or how tight could I tighten something down before the holder things would rip out of the roof? If no one suggests that, would you have any other suggestions that I could use to try and maximize all of the space I have and/or save space. At first I thought we would be ok and we may still be, but as the time gets closer I keep looking in there and try to visualize packing and it is going to be real close. I honestly may not have enough room for everything that we need to take. Thanks for any input that anyone may have.
