FYI for all, defective Tank Design!!!!
First I am so $^$*&$% at this forum software. My initial reply was lost as I did not hit the submit button and lost everything I typed while adding the pictures.
MY PDI dealer left the fresh water tank apx 1/2 full. 20-25 gallons (8.35 x 20 = 167 pounds) of the supposed 43 gallon (359#s) tank. From the pictures you can see that my fresh water tank supports collapsed and the plastic tank "oozes" through.
The tank is designed with 2 lateral (front and rear edge of tank) and 2 fore and aft (apx mid tank) 1.5" x 1.5" x 1/8" angle iron supports. The fwd support is welded in and the rear is bolted in. The 2 fore and aft supports "slide" into a slot.
I contacted FR and they were 100% cooperative as they seemed to expect calls on this design issue. It seemed to me that the designers did not think anyone fills their tanks completely. FR offered to send me new replacement support parts, but the defect problem would just repeat itself!
I offered to R&R, Redesign and Install a proper solution. I cut out the collapsed fwd support and removed the tank. I installed Q2 - 4"x3"x1/4" aluminum T bar fwd and aft lateral supports and Q5 2"x2"x1/4" fore & aft tank supports. This eliminated all "oozing" and 100% supports the filled tank weight. It is also SS bolted vs welded it in allowing for future tank servicing and/or replacement. This solution only added a net of 20 pounds to the TT original supports. I could have eliminated some additional weight with "circles", but not necessary.
- The water hoses have TOO few clamps and WILL pull out from the floor. Mine did. I installed additional hose clamps and Tie Wraps too.
- The waste tanks have this same design defect too. They do not even have fore & aft supports. Some Good news, they only have a 28 vs 43 gallon capacity. I will NOT exceed 10-15 Gallons when ever possible before dumping!!!! I will not drive with anything over 5-10 gallons.
- My R&R Design eliminates hose up and down nearly eliminating vacuum problems, but the tank is still only capable of being filled to apx 38 vs 43 gallons.
