Hello, I have recently purchased a pickup truck, and I would like to use it to travel to launches. At the moment it has a cross bed tool box. I plan to get a tonneau later but as of now it is open. It is an 8 foot bed but I do not see any tie downs. I typically bring my excel, big nuke, some 2.6 and 3" mpr, and a tote of Lpr and a tote of motors/etc , toolbox and a folding table and a chair. Can I load up the bed without lighter stuff flying out? How do I tie stuff down? The trip is about an hour mostly on interstates . It is a regular cab. Or should I just wait to get a tonneau and keep using my other cars? Thanks for any input. I'm a first time trucker so I just don't know these things . It is a 91 f-150 in case that helps.
