## Questions & Answers

**Q: How thick is the plastic that the tank is made of?**
A: Average thickness 7/32” +/-

**Q: Can i stand this up so that the 39.5 inches is the height? If so, is the tank strong enough to withstand over the road travel or will i need to suppor**
A: The tank is strong enough, but all the plumbing holes would be on top of the tank. Why not buy a tank that's designed to be upright like the High Country 1/4 round or 1/2 round vertical tank. Something like this one. https://www.amazon.com/High-Country-Plastics-SL-39-gallon/dp/B0042L749S/ref=pd_sbs_86_3/143-1446200-0535447?_encoding=UTF8&pd_rd_i=B0042L749S&pd_rd_r=714f569d-d145-4695-bdcf-ab4025c53550&pd_rd_w=uEw4N&pd_rd_wg=kF6i5&pf_rd_p=52b7592c-2dc9-4ac6-84d4-4bda6360045e&pf_rd_r=W2Z3ACWY9QYJ9KQY4RC7&psc=1&refRID=W2Z3ACWY9QYJ9KQY4RC7
