Here is a thread on the subject on the LF Forum. I'm in there post #12 with a babyjogger and my 7x17. http://www.largeformatphotography.in...ghlight=Jogger
A lot depends on the terrain you want to cover. Over a few years I've done a series of 150 contact prints of the OH & Erie Canal. This means a towpath and easy walking. I can push the rig out two miles from the car and then back.
Look through the whole thread. There are lots of different approaches. One or a combination of a few may fit you needs. Glad to see you are still trying. When you stop trying it all falls apart.
Here is a Jack London piece on attitude.
“I would rather be ashes than dust! I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot. I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet. The function of man is to live, not to exist. I shall not waste my days trying to prolong them. I shall use my time.”
