Congrats. The smaller RV makers often do running changes during the model year run. Some for the better, some for the worse. So it's nothing unusual. LTV is also one of the small makers that will do unit specific to that unit only changes if they're not too radical from the norm.
What year is the chassis of your unit? RV's are often made on the previous year's chassis to the coach builder's year. You may already know this.
Advice, unless you know when it was done last, change the oil and all the filters. It might be due for a coolant and transmission service too, as well as the brake fluid flush
