What size grey and black water tanks are available as replacements for the rear tanks on a 2011 Keystone Montana Mountaineer 346LBQ? What are the prices and current lead times for delivery?
The 2011 Keystone Montana Mountaineer 346LBQ originally comes with approximately 93-gallon grey and black water tanks each, but actual tank size and shape may vary due to space constraints. Replacement options include 31-gallon and 42-gallon tanks. The 31-gallon tanks come in two dimension variants (27.5" x 20.5" x 17.5" and 34" x 19.5" x 13") and are suitable for mid-sized rear compartments, while the 42-gallon tank offers capacity closer to the original for extended use. Since tanks may be combined or split in the original setup, measuring your current tanks is essential before ordering. Pricing and lead times vary; please contact Elkhart RV Parts directly or visit their website for up-to-date cost and availability information.
