Hi Cliff - Was not my intent to tick you off
! I did state that they do cut down on the heat gain, and they certainly do. But having had both, no question that the exterior mounted shades offer a much larger reduction of heat gain - that is a fact, not opinion.
And we're in the South West, so have some areas called deserts. Have been in temps in the teens above 100, with both the Bounder (internal off white suction cup shades) and the Country Coach with external medium brown shades. So have experience in hot weather too.
I salute the DIY approaches, but do recommend if someone is just starting to develop a front cab shading system, that they do so with the External Shade approach. The few negatives of being wet or dirty from time to time when taking down to put away, has never been a problem. The material is very durable, and is easy to hose off and drys quickly when needed.
I do also recommend the magnet type approach, to avoid the need to snap the top via a ladder. Some DIY magnet shades searches will yield good results on How To.
I will also point out, that my DW had a bad back for several years (Surgery has made this 85% better now
!), and she had difficulty mounting the Bounders inside window shade suctions, especially above the driver seat. Where as she could mount the external the few times she did for me. (I had a broken hip, that for a few months made this her job.) So that is another, admittedly unusual, advantage to external shading.
Best to you, and all - do what works best for your circumstances. Desire to DIY, or amount that you are willing to spend
