I used to have an 05 KK Escape and yes they were the base model ( which is now the Sports RV )
One difference was the lack of the gullwing front box, instead it had the smaller box with the slide out cooker.
Also the Escape had electric brakes and leaf springs ( and shockies ), but that wasn't a bad thing....it still rode and handled very good ..
Came standard with only 2 batts ( 70A/H ) but it could be upgraded to 6 batts if you wanted !
Another thing was a 70 ltr water tank ( instead of the stainless 120 ltr )
As no two trailers were never usually the same as they left the factory, it could have some/ none or all available options ??
The tent, main trailer, chassis was all the same, so apart from the above things, you won't feel as if the quality is less than the top of the range models..
Check for general condition of the whole setup ( especially the tent section ) and good luck with your "maybe" purchase !
