| Bass and hook? Wherezattt?
In general, I try to use my Subaru Forester instead of my Nissan Frontier, but when I do have to use the truck to transport the bass, I lay something soft down on the bed (foam, in my case) and place something under the neckblock area. I use my gig bag, but a rolled-up towel would be okay. This lifts the scroll up off the bed so it doesn't put stress on the neck. The bed cover I have is pretty cool; it's an Extang Fulltilt, which can be tilted up, rolled up to the cab end, or removed entirely in a matter of seconds. That way, I can still use the truck to haul big loads if I need to.
Of course, when the truck stops, the bass comes out and goes with me. One thing I've noticed; when you shut the truck off, the truck bed gets pretty warm from the exhaust passing right under it and allowing the residual heat to rise up throught it, so you wouldn't want to leave the bass in there for any length of time.
The other thing is; try to choose your route so that you avoid as much twists and potholes as possible. Trucks like my Nissan and your Ford weren't designed to give a comfortable ride, so you should try to minimize the jarring as much as possible. |
