With luck, someone will be along shortly to answer your question based on personal experience.
In the meantime, what does the owners manual give as a tow rating and the tongue
weight rating. Remember this is the MAX, with the trailer loaded and ready to go.
Is there a different rating with
brakes, and is the
Casita so equipped?
I firmly believe you should always leave a 20% minimum margin of safety in there. For example, if your published rating is 3500 lbs, I would suggest keeping the loaded trailer
weight at 2800 lbs or less. The manufacturer is saying you 'can' tow 3500 lbs. They are not saying they recommend it, or that you should do it day in and day out, or that you should do it a freeway speeds. Playing somewhat conservatively should give you longer vehicle life; engine, transmission, suspension,
brakes, etc.
