I've seen the 'handle plugs' on a number of extension cords now, and it's a great idea.
I agree about certain repairs, Mike. Since my Dad was a cabinetmaker/carpenter, and being a wannabe engineer, I tend to take things to the nth degree...well, because I can and it makes me feel good. Those plastic things are more PITA than they are worth and they are usually stapled to the support while they are still somewhat pliable. Don't try to work with them after a couple of years, they turn to dust. I had a "drawer opens while on the road" gremlin and played with all the adjustments to the drawer glides including remounting everything. No luck. So, a couple of eye screws and a small bungee later....
As for my rebuild, for the guys that went thru it with me on this thread in December, turns out my misclick on the special hinge website came back to bite me, since the box top hinges which SHOULD HAVE had springs don't provide the help I need to hold the tops open. My DW now assists me after the seat 'bit' my hand a couple of times on the last trip.
Did I mention anything about fabricating some kind of 'drop down' battery tray?
