In my Spyder F3 writeup I was very critical of the limited storage of the Spyder. I found a cheap, good quality and versatile storage add-on for my Spyder F3 in the Dowco Rally Pack Luggage System for only $75. Do not get confused by the “4 piece” description- it is really just 2 pieces and accessories such as an inner liner for the roll bag, plenty of straps and a cargo net. The bags are sizable at 17″ x 14.5″ x 10″ for the jumbo pack and the roll bag 9.5″ round and 14.5″ long. Both fit nicely on the passenger seat and between backrests if you have them. There are many different secure points to tie down the bags depending on your seat configuration. If you are pure stock in your setup everything can be secured to the passenger grab rails. With a passenger backrest in place the main bag easily secures to it.
The roll bag velcros to the jumbo pack and has a waterproof liner that velcros to the inside of the bag. The bags are not waterproof but I plan no spraying them with a sealer to give them a bit of protection. The jumbo bag itself sticks up just a bit higher than the driver backrest and is even with the passenger backrest. With the roll bag secured on the top it is over the backrest but does not obstruct any of the views from the mirrors or turning back to look. I am really pleased with the bag capacities and can put a good 4-5 days worth of clothes, shoes and toiletries in the bags with no problems. I plan a trip using the bags in a few weeks and am not concerned with storage any longer.
