there is a rule of thumb and it is in the section above int he RV FAQ section. I looked it up for you and here is the copy. Using the "rule of thumb" of 20 feet for 110 inches of wheelbase and an additional foot for every 4 additional inches, remember that it is a rule of thumb theory and as stated above weight is oh so important. hitch set up is in there too, many things to work out.
