Here are the specs for the 39‑gallon S&B wheel‑well tank:
• Material: Rotationally molded polyethylene plastic.
• BPA‑free: Yes, it’s specifically advertised as BPA‑free.
• Food‑grade: Yes, it is described as food‑grade safe for fresh‑water use and TEI/RVIA compliant.
• Shell thickness: S&B doesn’t publish an exact wall thickness number, but their wheel‑well tanks are heavy‑duty, TEI‑listed rotational‑molded poly; wall thickness is comparable to other RV fresh‑water tanks (roughly in the 3/16–1/4 inch range), built to withstand vehicle use without additional reinforcement.
