I've been starting to carry my KU5200 on walks with a moderate load, to condition myself for backpacking and hunting. I would rather not use my actual camping gear for training weight (don't want to compress sleeping bag unnecessarily, for example).

So far I have tried a 5 gallon softside water jug, and 40 pounds of college text books. Neither carried well, as they bunched up low in the bag; and I worry about longterm damage from the book edges to the fabric. Any suggestions?

My son used to borrow one of my 40 lb bags of water softener salt when he went on ruck marches with his ROTC unit.

That is like what I use. I use 25# bags of rock salt that I use to de-ice the sidewalk. I wrap duct tape around two sheets of cardboard to compress it and keep its shape so that it doesn't all wind up at the bottom of the pack.

I've got a "pill" made out of PVC pipe into a kind of ladder that I fill with sand that weighs about 70 lbs when full, easily secured to my MMR frame and it won't leak, just screw on a cleanout plug... Bags work too, just patch/repair with a trash bag or duct tape..

I use bulk bags of rice (5, 10, and 20 lb, as needed).

A stuffsack full of old pillows in the bottom of the pack and an assorment of GI sandbags containing Hefty trashbags full of kitty litter. These are duct taped with the weight written on them with a Sharpie.

Take-a-knee's suggestion is good in that it pretty much duplicates the type of gear a pack is expected to carry and keeps it from shifting around.

Don't use dumbells or lifting weight plates or such. These put weight at one point causing wear on the fabric and straining the stitching. Backpacks are not designed for this type of cargo. Even 1000d Cordura will stretch and have the lining break down under such use.

I had the wife wrap dumbbells with towels multiple times to avoid the wear on her KU3200. Really want to avoid the wear spots that some items over time can create. She likes less than ten pound weights or less as it distributes more evenly over the entire pack to make it full. The Winds in WY will make you prep if you are from MI....

Either the 40 lb bags of wood pellets or a heavy duty leaf bag full of dog food.

Old tents. Of course you have to be old enough to have a large enough collection.

I used this technique to re purpose an old sandbag.

Put a heavy duty trash bag in the pack and fill it with water, twist the top and put a tie wrap on it ;)
3700 cubic inches is about 133 pounds of water, so fill accordingly :)

I just use body parts that need burying in the wilderness. <g>

Snap the pillows keep the weight further up the bag, weight at the bottom will kill your back.

...weight at the bottom will kill your back.

I don't necessarily agree with this at all, the whole philosophy of the Kifaru packs is to transfer the weight to your hips, not to your shoulders. The stays of the pack help distribute the weight to the hips. Lowering the center of gravity to the hips reduces the upper body effort required to support it. What kills your back is shifting the weight behind your hips (causing leaning forward to counterbalance, like with an ALICE pack) or up too high where the lower back, shoulders and abdominal muscles are balancing trying to keep your feet under the load.

Not knowing any better, I've been using one-piece dumbbells that are wrapped in beach towels. I would wrap a dumbbell in a beach towel, stand it vertically in the center of the bottom of the pack, then pack the sides with additional towels. to keep it from shifting. I would then put another layer in on that from the top, so that I wind up with two dumbbells up the center of the pack (about 20-24" in height), and no extra space for shifting. All total, I wind up with about 65lbs of pack that way.

I'll run 25lbs Plates along with some 10's or 5's depending on the weight required for the ruck-march we're doing. To ensure the load rides high I'll run a suspension line of 550 cord through the center holes of the plates and up to the top of the pack. Duck tape the plates together to ensure they don't slide around too much. Caveat is that I'm running a radio pouch ALL the time in my KU packs. That's what the plates sit in.

Now why in the world would a JTAC need a radio pouch??? :rolleyes:

Gotta have somewhere to put Copenhagen and Rip-its! If I can figure out how to post pictures on here I'll drop some pictures of my current rolling gear set up
