Customer Question

I ordered a 98-gallon fresh water tank (59x58x7) and a fittings kit for my 2012 Keystone Raptor 300MP, but now the link shows a refrigerator part. What happened and which tank should I order?

Expert Answer

The 98-gallon fresh water tank you selected (EPI 3038 / W1435) measures 59" x 58" x 7" and is designed as a direct fit for most Keystone 100+ gallon systems, including your 2012 Keystone Raptor 300MP. It is a blank tank that requires a separate fittings kit to complete installation. The link confusion may have occurred due to a website error or incorrect URL. To ensure proper fitment, verify your existing tank dimensions. If your tank thickness is closer to 7", the W1435 model is correct. If your tank is taller, approximately 15" thick, then the alternative narrow/tall 98-gallon tank (EPI 171W, 64" x 26" x 15") is recommended. You can complete your order directly through the provided checkout link and use code ALIRVP for $5 off and free shipping.
