We have a rear kitchen 2007 Tango, RKS2660.
The rear kitchen is what sold us on the purchase.
We had a 1995, 9-1/2 ft Lance camper, for a good number of years and loved it.
Then the wife had trouble climbing the vertical "ladder" to the bed over the cab so we needed something else.
The floor plan is great and in all the miles we have pulled the fifth, no issues with things falling out of the reefer or the cupboards.
Many trips to Washington, Idaho, Oregon, California, Wyoming, Nevada and Colorado
We had also heard the "horror" stories of things falling out of cupboards.
The coffee maker stays on the counter top while traveling and it is still there when we stop.
