Elkhart RV Parts offers the 48.75" x 31.75" x 4.5" RV water tank typically shipped without any holes, allowing you to customize the placement of fittings as needed. We do not provide custom modifications to tanks for hole placement prior to shipping. You can purchase the tank blank and install the fittings yourself or use our professional Custom Fittings Install Service, where up to five fittings can be spin-welded into your tank for $208.33. For your specific fitting locations, you would supply the fittings, and we can install them for you. Lead times vary, so please contact us directly for a shipping quote to Canton, GA. You can also use our Tank Finder Tool to explore other tank sizes and styles that might better fit your configuration.
