Does anyone have experience with these? I'm thinking of getting one to add fuel to my bike. I have a 4.1 safari tank on now and would like the extra fuel from time to time instead of using my 6.6 gal tank. I'm not going to plumb it in, just use it to carry fuel and dump it in the main tank if I need it. I wont even leave it one the bike. Mostly looking for feedback on how it mounts and can it take abuse.
