Download the MSRP from the forum. It will have all the options and you can choose from them. Then you can add up the base and all option $$$. At times their are options that may not be on the MSRP...your dealer can find out if their are other's. OR, you can HL yourself, ask for LM sales and ask for yourself. Then take 30% off that number and then go make your deal. Dealers mark up trailers sometimes $30K or more than the HL MSRP. BTW, taking the 30% off is reducing the cost of all options.
