we have used the reflective bubble wrap inside the unit for years...it works well, but it stays in place for about 2 weeks(when we have to unclothe ourselves to water/dump)...I would dearly love to create a a nylon cover on spring rods that would cover our rig with about a 2 foot space of 'blanket' air...a small, and often solution offered by me, is that when you are boondocked or even full-serviced in warm climate, is get a spring-loaded curtain rod, shower curtains to suit your style, and mount them just behind the front seats...this will aid you in cooling while traveling with dash air, and it will cut down on roof air requirements when stationary...tacky...well, maybe, but efficient...you are enclosing about 30 SF of window space on the road, and excluding that much area at night...the 345 is notorious for a failing dash slide from heat to cool...facing the front of the rig, with the hood bonnet open, the slide is reachable on the left side, behind the rubber screen...hard, maybe, to find at first, but once found...you got it....it slides right or left...let someone inside tell you what they are doing with the slide...not rocket science, but a bit hard the first time, till you get the gist, then it's simply rote...the rote can be altered by really rainy weather, hail, or night time...BUT. find the slide on a good weather day, and all that other stuff will come, even if yer wet, beaten by ice, or blinded by dark...
If you can swing it, awnings all the way around will help a lot
