Purchased a 2012 Bighorn 3685RL from ExploreUSA RV of Texas & had a "Whirlpool" stackable washer/dryed installed. The washer vibrates excessively & the first load (small) in the dryer was still damp after 30 min.,upon inspection I found that the lint filter was packed solid with lint. Looks like EXPLOREUSA RV sold us a used unit..Another reason not to deal with these people !!!!!!!!!
