Beginning

So I have decided I want to get into bikepacking, seems like the perfect way to combine many of my passions. The thing is, I dont want to buy a new bike, and so I need ideas and resources for how to use what I have. I'm not exactly an ultra light camper when backpacking, and would prefer to maintain that when bikepacking. Depending on where im going and how long, my kit generally weighs 50 to 90 lbs. My current bike is a Giant Trace X 29 2, so not alot of places to mount things. Im thinking a cargo trailer like the burley coho or quietkat might be the best solution out there to suite my needs. Any other ideas, options, or opinions?
