Boils down to 'decisions' and 'compromises' that all designers/engineers must make
The solar array will 'shade' the trailer and if you have an air gap, the temp
differential will be or should be high enough to keep the trailer cooler in full
sun. The sides will then become an issue, but that goes back to
the 'decisions' and 'compromises'...
That 1K of batteries is always a problem for storage on mobile vehicles
If the TV has more payload capacity, then there...or a bigger or different
type of architecture of trailer...toy hauler maybe?
CDR's (Critical Design Reviews) should not be personal and I do NOT or am NOT
dissing this
One of my design philosophies is to ask everyone, including myself, to toss
stones at mine or teams design until the stones bounce off and/or the breakage
is acceptable...
