MWard86,
It may be that the local King Koil licensee doesn’t share more detailed specifications with the retailers in your area. It could also be that your local retailer isn’t as interested in that information. It could be a combination of both. There are plenty of nice retailers out there who can’t or don’t have access to the information you need to make an informed shipping decision. If you were buying a car, you’d demand to know what type of engine was on the inside.
For a higher BMI, there’s a popular reference post #3 here that has some guidelines for higher weights you might find interesting.
