I've only had one awning and it came with my bus, so i'll pass along my 2 sints
Mine is manual, top clip mounted to drip rail,
lower brackets outside the bay doors
can disconnect to use in "carport mode" and stake legs to ground.
i like to sit outside in the rain, learned about leaning it the
hardway and filled up the awning and stretched it, now it gets water inside and turns black
i like not hitting my head on the raill when attached to bus
If i was doing it now:
- figure out a way to get it over the door
- get the cover, or the material right at the bus that is always exposed to the elements to be made of metal/alluminum.
find Oddeseys web page and check out his awnings and streamlined end caps, mounted on top of bus and no side arms
if you splurge on automatic, the mrs. can put it up(sheel feel more independent
Ross had a pretty good set up too, powered, no down legs to hit head on, mounts to side of bus.
good luck and let us know how it turns out
