I'm wondering what Read & Learn's repsonse has to do with the topic.. or is it a case of wrong thread?
That product may be good for a verticle wheel like in a car. but on the more "flat" wheel of my motor home.. Not so much
I did take a piece of plywood, cut it into an octagon (like a stop sign) and attach a cople of strips on the bottom that "hook" onto the top of the wheel and on one more at the bottom on Top of the "Table" so my laptop does not slide off.. With the wheel in the FULL UP position it puts the laptop at just about the perfect angle for use.
I plan on a minor modification to this to use as a printer support shelf when I get the needed cables made up for the printer.. But I've got to find the blanged connectors first
