The wife and I don't have kids but we have the 351-THSS. We do have two motorcycles and sometimes friends (haha!!!) We went with this model because of the dinette. we came from a very small toy hauler model that required we always fold up or down the dinette and sofas so we did not want to do any of that. Garage is almost 12'. Total length is 37'. empty weight is I think 9700 and tongue weight is 14xx.
The price was really affordable for us and we really like the layout. I would have purchased something with fiberglass walls but my first toy hauler has some delam issues and for the time being I'm kind of turned off but there are many that have had zero issues. anyways, I digress.
11' 8" garage with pleny of tie downs. I however replaced the self-tapping screws with thread type screws and nylon lock nuts.
