Good points, Tom, on bugs and rocks. I was originally thinking tempered glass or something like Plexiglass but laminated safety glass, like the windshield, might be necessary. If a narrow one fit ahead of the PC door, that sounds more feasible. I'm trying to sort out different issues on various rigs of different types, even including the last of the Rexhall Vision / American Clipper that included a 24-foot model on the love it / hate it Workhorse version of the P30 or the 26-foot Airstream Land Yacht (Thor!) on the more modernized (wide track and the 8.1) Workhorse version of that chassis, both small enough to avoid the dreaded GM autopark brake issues. Of course, these have a more open feel inside than many Class Cs and "B+", incuding PC; hence, my inquries re. more windows. That Ron and others would know of some with another window on side is helpful. Thanks!
