I got my Silver Mountain Solo and thus began the frame build.  SMT provides a plan but I tweeked it in size and features that anyone can do easily.   
First I didn’t like the size of theirs. It’s too wide IMO because I want it to lay flat in my truck bed so I set a limit of 48”. So I basically built their exact frame except it’s narrower.
Before assembly I used my table saw to cut a 1/2” wide by 3/8” deep rabbet on each upright full length. Can be done with router too. At this time I also cut a rabbet in 2 1x4s which is the only extra material from the SMT list. A single 1x4-8’.
I then glued and screwed the frame as shown adding a 37” 1x4 at the bottom. This gave me a 37”x37” target opening for a 38”x38” piece of coroplast. The 1/2” wide rabbet on each side is why the coroplast is 1” bigger. Since I only plan to use 300 and 500 f class targets this is perfect.
For the top 1x4 I cut it a touch under 38” for some play and cut rabbets in each end to slide into the side rails over the target.
I slid in a blank piece of coroplast and my glued up face coroplast so there are 2 to stiffen it and fill rabbet.
I then set up the sensors and antenna and used plastic 3/4” wire guides to keep the cables organized.
Works great and takes seconds to change a face. I created a big X on the coroplast that will always be dead center of the target when I glue up new ones so calibration isn’t affected at all.
Just thought I’d share. Took less than 30 minutes to make once I decided on the size.
