Help with Crawmerax!

I need help fighting Crawmerax, I am under level (43 Mordecai as of time of post) but I want to fight Crawmerax for the trophy and also just to get it over with, so if youre a high level on Borderlands 1 and you want to help then add me on PSN: DarkAurora2502

(You can keep loot if you want)
Thank you!
