I'm with Wayne on this. You might want to consider a different chassis in particular with consideration of your desire to tow a heavy vehicle. The Freightliner chassis the Palazzo is built on utilizes a Cummins ISB engine paired with an Allison 2500MH transmission. Although adequate for the size coach the Allison has a gross weight limit of 33,000 Lbs. I don't know how much an empty Palazzo weights but you really don't want to over stress the transmission. Over heat it a few times with a heavy load and you might be facing an expensive rebuild.
If you can find a coach within your budget with an ISC version engine and 3000MH transmission I think you might be a bit happier. Just because the builder installed a 10K hitch doesn't mean you are good to that weight. Run the numbers to ensure you will be within all the various limits. I am a bit surprised Thor installed a hitch of that size. Most rigs built on this chassis have a 5K hitch such as a Tiffin Red or a Coachman Cross Country.
