Hi One
Thanks for the interest!
Ok, so this one took quite a few failed attempts to get the right cart...
As I travel solo, the prime function is as a GBHB if I become immobolised far from assistance, I can walk out (It's my back-up-plan)... Yip I know 1 plan is none 2 plans is 1 plan... but....
So anyhow. To your questions. having given the prime function, it stands to reason that, I would walk back the route which I drove to before I got stuck. Given that, most of the way would be some kind of track / gravel-road, and, I would assume, most of the distance I have to go so I won't have to tote the weight for most of the way.
I've tested it out on twin tracks & gravel roads and because of the big wheels it actually copes quite well.
When I need to tote, it folds down (and here is one of the factors to get right with the cart) to no wider than my back-pack. Yes, there is a compromise in additional weight, but itits hardly worth worrying about, the cart is very light.. (that's the second factor to get right) very light weight. I'm happ with the compromise of a little additional weight over the ability to cart the weight... If you get what I'm trading.... (a little heaver when I have to tote <over> on weight to carry for most of the distance.
Then the bag is removably strapped on. That gives me the option of removing the cart altogether, concealing it for later retrieval, and going forward with just the back-pack.... This is nice, because on the odd ocasion when I do want to hike (like I did at Golden gate <Google that> I have a 72H completely kitted out hiking bag with 1 man tent <shelter> and all the rest of the stuff one would need if hiking & intending on sleeping out.
Ok so now we come to C of G...
When carting the bottom of the bag sits over the axel. as you know all the heavy stuff is always packed at the bottom, so this counters the balance and it has only a slight "positive" <downward> weight. In the bag above the main bag is only a thin hiking sponge sleep-mat... if its 300G it's a lot, so there is actually no weight worth worrying about. This was also one of the factors to get right when finding out which is the correct cart....
The problem I do experiance is "torque" force on my torso, created by the rolling resistance of the cart being pulled along with my hand / arm. It's a bit of an issue as I've got to keep changing my stick & cart from left to right arm.
I've got something in the pipeline to make a harness so that I can tow the cart behind, this will then also enable me to use both my sticks, whaich, as yo would know is waaaay happier, .................... But it's beet booted down the let's fix this priority list.......................... Which's got a hundred and plenty things...........
SIGH............. Think we're all there.............. Somewhere................... The let's fix this list...................
Ok so for storage in the roof-top-steel footlocker, the wheels get taken off <cart comes with a simple clippie thingie on each wheel to take the wheels off>, the cart is folded and the whole shebang goes into a zip-up duffel bag and into the footlocker...
Pneumatic tyres... Haven't considered, as the cart came complete and as I post, I think it would add a LOT percentage wize to the overall weight of the cart...
If the purpose of the bag was other <dedicated hiking> I probibly may have ended up with something different in some respects...
