At RecPro we sell many tanks that are basic blanks.  We do this because there are so many models of RVs, concession trailers, small homes, food trucks, and toy haulers out there that finding an exact mold to fit each and every variation would require a warehouse the size of an NFL stadium.  Even if we had that much storage capacity, there would still be that one-off unit out there that needed something unique.  That’s why our custom blanks from Alpha are designed to fit many models.  But, what if you’re that very specific one-off?  What if your application needs such specificity that you would be hard pressed to explain the design to an engineer?  Don’t worry, at RecPro, we’ve got you covered.  You can say ‘tanks’ a lot later.

The VR304565W 18-gallon fresh water tank from Alpha is made for a complicated well or installation under-frame.  The “L” shaped body (or “J” depending on your mounting condition) is made to specifically fit certain models of recreational vehicle.  It has a generous storage belly with extra capacity in the shelf to maintain storage area even with a complicated mounting area.  While it is constructed to fit a unique area, it still maintains the high-quality standards at Alpha they apply to all of their tanks.  Thick high-density plastic walls with low-adhesion surfaces that are BPA free and certified for clean drinking use, these tanks are made to fit your needs.

If this tank fits your needs, call our Customer Care Department today and order yours today.  Be sure to clarify lead times as this is a custom order piece!
