Hi Judson,
I plan to incorporate my dew control and wiring into a box that rides on the front end of my rocker box similar to this made by Doug Scobel:

I don't remember if you observe from home or if you ever take it to dark skies, but if weight isn't a problem I suggest two layers of 3/4" plywood for the bottom of the rocker and place the sides on this base. Before I'm flamed for overkill the extra weight is definitely worth it for the increased stability of the mount.
My truss scope is easy to wheel up into my Chrysler mini van and is rock solid for observing. I get no flex or backlash at all and using an Argo Navis with just a casual alignment I can put objects into a 100X EP almost 100% of the time. I (over)built mine using the Kriege and Berry book and used 1" sides for the bearings and 1/2" for the front and back and I'm glad I did. Maybe someday I'll rebuild it into a ultra light.
Oh course, yours is for a tube newt and the rocker has to be tall for your altitude bearings, so you could use 3/4" plywood and use side braces like Floyd Blue has done and posted to stiffen up the rocker sides. I'd still use the double thickness for the bottom.
Keep us informed with how your project is coming along.
Why not go all the way and rebuild it into a truss?

I leave it assembled in the garage and roll it out to the patio for observing.
