You're welcome AsheGuy.
The one RV/trailer places I stopped at to buy the J-pin showed me the same hitch tightener that McZippie uses. They said that was all they carried.
Heater fuel tank installation continued -
Lately I've been spending so much time below the van getting measurements, working, painting on rustproofing and other things that I no longer think of it simply as the space under the van. It is now "The Undervan".
With the undervan measurements on hand I now needed the side dimensions. The inlet for the fuel tank will go through the side of the van. I don't know where the rocker panel ends and the side of the van begins or even if this distinction holds with a van. I couldn't find any kind of a cut-away diagram.
So I need to know the width of the side of the van in relation to outer edge of the undervan on the drivers side. I'll be using a drywall T-square, clamp and tape measure.
No we haven't had a freak snowstorm in WV. These pictures are from when I first did this back in February.
Clamp on the T-square using the small lip at the bottom of the rocker pane as an anchor point.
The cross part of the T-square is against the inside edge of the rocker panel (aka the outer edge of the driver's side undervan).
With what I think of as the upright part of the T-square now extending outward from the van I have a graduated baseline for measurements.
Take the tape measure and and find the distance from the top edge of the T-square to the edge of the van. Write it down.
Using graduations on the T-square as a guide, move the tape measure a half inch farther left. Then get the distance from the edge to the van. (In the picture it's moved an inch but you get the idea.)
Keep this up until you run out of van.
As usual I was under direct supervision.
Take all the measurements and plot out a cross section of the rocker panel.
The line on the left that represents the outer skin of the rocker panel is far from exact but it is close enough for my purposes. You can see a measurement of 6.17" under the line. If you extend the line of the floor to the left into the rocker panel space this what the width should be at this point.
But that was still the big unknown. What's really inside the rocker panel? (Don't bother telling me. I now know.) Even without that information I can use this drawing and the one from the previous post for sketching up different fuel tank and inlet configurations.
