Class A without leveling jacks?

Leveling jacks are almost Standard on Motorhomes with slide rooms. 25 years ago, they were an option. Then when slide rooms became almost standard on all models they realized they needed Jacks to keep the RV from leaning to the side of the slide room. Originally you NEVER had a slide room on the Pass side. Always on the drivers side. That caused the RV to lean to the left and be out of a normal level. With the increase in slides on both sides and the COST of Class A Motorhomes increasing, they realized that leveling jacks were almost required. Dealers also realized they were at a disadvantage when selling a Class A without Jacks. Other dealers would point out the advantage of jacks with the slide outs and the cost of adding them would be more than what the Factory could install them for. A lot of entry level motorhomes(A and C) may not have Jacks and it is an option and to get the customer in to buy, the price point can shave almost 3k to 5k off the selling price. Then the dealer can upsell if needed. I would have leveling jacks on my motorhome. It WILL increase your used selling price whether trading or selling outright. Doug
