With a portable system, I won't have to pierce the roof and I can orient the panels to morning or afternoon sun. What have you found that works?
#1: Roof mounting is (usually) not a problem. If anything, it won't negatively affect the resale value of trailer that is more than 1 year old.
#2: Yes, you could orient the portable. More over, you'll HAVE to orient the portable because it will be tilted, therefore susceptible to drop in output when sun goes behind the panel. With flat on the roof there is no such problem. 22' trailer should have enough roof space for 300-400W. 300W flat will collect more energy than 150W tilted/oriented portable.
#3: With your stated needs anything over 140W will work. Larger portables will be more logistics pain, setting it up every time. Any portable would imply setting it up, be it big or small. You want panels outside, and yet you want controller covered from elements, which (usually) means placing it inside or in storage compartment. You also want to tie panel down so that wind wouldn't flip it up.
