If its going to go overland / or travel get a pelican or storm case. The #1 killer of lenses / cameras is the constant small vibrations cause by a car simply going down a paved road. Put your truck on dirt roads and your sure to start knocking things out of alignment such as the elements of a lense.
This may be true, but was not our experience in traveling all over the world by motorcycle. Our cameras and lenses lived in LowePro backpack camera bags inside pannier boxes mounted to a variety of motorcycles, including ones with 2-3" of rear suspension travel such as this Royal Enfield Bullet.
We traveled over all types of roads, from freeways to rocky, rutted tracks.
I used a LowePro Mini Trekker AW and my wife used a LowePro Dry Zone 100.
My wife carried a Canon 10D, Canon F3.5-5.6 28-135 IS & Canon F4.5-5.6 75-300 IS. I started with a 10D and then switched to a 1DMkII when it came out. I started with a 35-350 and switched to a F3.5-5.6 28-300 L IS when it was introduced. I also carried a Canon F2.8 16-35mm L & Canon F2.8 24-70mm L. For one trip I had a F2.8 70-200mm L IS (brought by mistake, long but funny story) and on another a F2.8 100mm Macro. We also carried strobes, remotes, etc.
We never suffered a single failure of any piece of photographic equipment.
I would recommend an AW (all weather) type bag, whatever brand you choose. At least get a bag with a weather cover so you can shoot and travel in rain.
IMO the extra weight of the DryZone is not worth it unless the bag is going to be exposed to the elements, i.e. carried on the outside of a motorcycle, instead of inside a pannier box or a vehicle.
The handiest bag we have is my wife's LowePro Orion Mini. It's the perfect size for her 30D & F3.5-5.6 28-135 IS some batteries and memory cards. That whole ensemble is a fantastic setup, very light and very capable.
For size, we have found the LowePro MiniTrekker / CompuTrekker / DryZone 100 is the largest size that will consistently fit in today's airline environment.
Since our bike travels we have both switched to the LowePro CompuTrekker AW (the laptop version of the MiniTrekker AW).
We're both bag addicts (hello, my name is Doug and I am powerless before the bag...), so it is very dangerous when we visit a camera store or a trade show. We have owned and currently still own a very large selection of camera bags, including a couple of larger LowePro backpacks. I primarily use them to store my lenses & extra gear. I am so used to it, I only shoot with the CompuTrekker AW.
I think there are a lot of great bags out there. We standardized on LowePro so that all the accessories, add-ons, etc. would work within the same system.
Also, don't pass up on the opportunity to re-purpose the bags. We used two LowePro Stealth 650 AW bags to hold our clothes. We mounted them on top of our pannier boxes, shown here in front of a restored Samari home in Japan.
Note the LowePro lens tube on the forward end of the 650. We had one on each side that my wife used for stowing the video camera, water bottles, her gloves, etc.
When it rained we used the 650 AW rain covers to protect our clothes.
Again, I think there a lot of great bags out there by a variety of manufacturers. We have found LowePro products to be very reliable and versatile.
