I have the Kobiak 279rbsl. My DW and I love it as the floor plan is perfect for us. I have had to replace the A/C within thirteen months but that is the only issue we have had. It trailers very nicely behind my Ford F-150 and is easy to get into campsites. Not sure how many camp with you, but I would recommend the Queen size sofa sleeper over the jackknife couch. The sofa sleeper is very comfortable as we have had our grown son and his wife sleep on it as well as friend's of our. All have said the sleeper was very comfortable. Good luck with whatever you get and many happy memories.
