Welcome to the Forum!
I think you will find that most questions about your RV need to be answered by looking at the specific item in the RV. These RV maufacturers use a various number of suppliers for most RV furnishings so you never know the specs of your RV item unless you look at it, measure it and get the manufacturer's name.
If your RV is a model BHFK 33, suggesting that it's 33 feet long, it could be 32 feet long or 34 feet long. You need to measure it. The tires your RV comes with can vary in manufacturer, as can your appliances, your mattress, your sofa-recliners and any TV's.
You almost always have to look carefully at your your specific RV to answer these sorts of questions. The same model trailer can feature different equipment in the same model year. Manufacturers try to cut costs at every turn, especially with things like tires, furniture, or mattresses.
You'll get to know your RV inside out. We wish you a great summer of camping!
