Sorry for all the noob-ish questions. Are you saying they are the same tents, just with a different label stitched on?
Yep, exactly the same as the ARBII, there is an ARBIII now but that design is still under licence so isn't being made with another badge yet, I reckon 90% of Australians that buy roof top tents get the Ebay ones as they are sold locally and are substantially cheaper then the ARB tents etc. Apparently the ebay tents come from the same factory that makes the ARB tents as well.
Here's an ARBII
Here's mine mounted on my teardrop trailer
Instructions are the same, interior etc is all the same, even the quality of canvas etc feels and looks the same. Spares are also interchangable
Cheers
