Drip edge and gutters on new rv roof

I’m a total newbie intent on reroofing my fifth wheel trailer. We’ve ripped off the old crap and replaced the soggy osb with plywood. We don’t plan on ever moving the thing and live in a wet climate w lots of falling pine needles. Our local roofing supply suggests rolled torch down (w/ a nailed down base layer) as the best solution considering the conditions and low pitch. The existing gutters are too small and would be covered up by the drip edge of my new roof. Does anyone have suggestions on how best to apply drip edge and gutters in this situation? What would be a good size and shape for them? Thanks in advance for your help! :slight_smile:

If it’s parked, build a roof over it.
The actual roof is unlikely ever to be reliable.
