As I research Toy Haulers I've noticed some have higher hitch weights than others that weigh less. Why the variance and how much of a role does that play when shopping for a TH? For example: KZ M...
From your posting, 900 to 980 lbs is not much of a variance IMO..
Its all on the options that make the weights different.. ie: King bed vs queen bed in front, Configuration of dressers or nightstands, overhead cabinets, slides....etc...
80 lbs one way or another should not make a difference with regards to tow vehicle or shopping if your looking in the 1000 lbs range of tongue weight.. If it does then you have other issues with regards to payload capacity.....
