We have had four awnings. Two with panels that fix to the wind out awning, and two driveaway awnings.
1. Comfortz awning panels
Pros: small pack size, cheap, quick to erect
Cons: small, drafty, no groundsheet, need to pack away to drive away
2. Thule residence
Pros: can be heated with the parking heater, makes full use of wind out awning size, robust
Cons: bulky, expensive, needs packing away to drive away, no groundsheet, fiddly to erect
Vango Kela III
Pros: large enough for kitchen area, dining area and storage; option to buy a bedroom; sewn in groundsheet
Cons: bulky
Vango hexaway
Pros: elegant, big windows, single inflation point, high, huge, clip-in groundsheet
Cons: bulky, clip-in groundsheet, not fully suitable for sleeping
We currently have the Vango Hexaway and Thule Residence and will continue to use the Residence for weekend camping and Hexaway for holiday camping. I do really like the Hexaway, it is so big, bright and airy, and it looks good. It has the feel of a gazebo. It fixes to the wind out awning via a channel, and can be used with the canopy fully extended, fully retracted or anything in between. Our usual setup with a driveaway is with the canopy extended, but you get more privacy with the canopy retracted.
The Residence is also a great design, but painful to set up and pack away.
