Customer Question

Is there a specification sheet available for the Thor Motor Coach 32-gallon grey water holding tank model TDW0200 (old SD0687), or will a custom fabrication be necessary?

Expert Answer

Thor Motor Coach does not provide a direct replacement or specification sheet for the 32-gallon grey water holding tank model TDW0200 (old SD0687). Therefore, a custom fabrication may be required. However, there are alternative holding tanks with similar dimensions and capacities available, such as the 42 Gallon EPI 4430 (84" x 23" x 12"), the Alpha 60 Gallon 769BLANK (62" x 32" x 8.75"), and the ICON 30 Gallon HT140-SD (60" x 24" x 8"). You can use our online Tank Finder tool to filter tanks by your specific size requirements and find the best fit RV. If your tank dimensions are critical, fabricating a custom tank locally might be the best solution.
