I pull my 560 with a Wrangler Sahara JKU - typically get 19 - 20 mpg which isn't much of a drop over std. mpg. Don't really notice that I am pulling a trailer, other than seeing it in the rearview mirror :). I believe the Gladiator has more towing capacity than the JKU.
There was room for 2 chairs under the awning - here is a link that gives you a better idea of how the awning looks - it was really designed for vans and SUV's -...
Recently picked up the Kelty Sideroads Awning and used it the first time last week. Fit the camper quite well and we were able to open the galley lid all the way up with no issues. Was very satisfied with how it worked. Easy to set up and take down.
Don't have a phot0 of it set up and we have snow already. It is the one they no longer make - in the original bag. Only set up one time and has been stored in the camper. Would ship from 49707.
I have a REI Alcove with one windwall - like brand new - only used once - ran into some family heaith issues after I got it.
$100 plus shipping. Shipping weight would be about 17 - 18#.
Might be late on this but don't get anything smaller than a 2 person tent. Also through experience get a size larger sleeping pad than recommended. It doesn't weigh much more and is much more comfortable.
REI, Moosejaw and Backcountry are good sources.
