Titan tanks are made of plastic. Transferflow tanks are aluminized steel so yes they are heavier. Both hold about the same (50 gallons and both are midship replacement tanks). T-flow are stronger, yet both can be installed right in your garage. Given their size, can easily go 300-400 miles before you need fuel or next CG, drop RV and buzz to fuel up w/o RV and still have plenty for reserve-----just in case. I had 2 T-flows, installed myself and worked great. Best part as well was still able to utilize front of hitch for stuff.....IE: firewood.
