On our 2012 Solera "S", I believe the slideout is the "Lippert Flush Floor". Info from Lippert:

We had a major issue early with ours - the motor mount broke off the frame of the coach. This was on about the fifth use after we received our Motorhome. I had asked the dealer twice before delivery to correct it's poor action - which he attributed first to low batteries and second to insufficient lubrication.
The mechanism is fairly simple and straightforward. the motor and connecting rods are visible from under the vehicle through the propane compartmenmt (motor is mounted above the propane regulator) and from the compartment behind the propane compartment.
I found an independent RV shop local to me that re-welded the motor mount and set up the slideout. It has worked flawlessly since that repair. Forest River pre-approved my use of an independent and reimbursed.
If you type "Solera slideout" in the search box you will find many entries.
