Certainly can help! but you need to be more specific....
I'm a backpacker, even relocating to Singapore I only carried one backpack, ok and one more suitcase
what you want to know? different countries you want to travel to you can use different types of backpacks....from 30L to 75L, or you want to know how to pack?
or you want to know what to bring? again, season wise, I brought mine from swimming wear to ski thick coat, from jandles to thick hiking boots...from camping gear to cookingware hahahah
tropical or not? medecine, you need all the jabs before you go , prevent all those illness...ie. malaria, hyp A, B...etc..etc..
pack light, put money everywhere, hide it, sew it within the clothe layer...etc...
there's so much to talk about backpacking.....WHAT YOU WANT TO KNOW mate?
