Review and Install Procedures & Notes.
Style: Low-Profile Size: 50 Gallon (58in)
Review Image by Serathias
**REVIEW AND INSTALL NOTES ** I'm not an RV professional, just my two cents as a guy that regularly fixes his own stuff. The tank quality itself is great. I did have to do a bit of extra plumbing(fittings reducing 1 1/2" drain port at the bottom to 3/4") Everything else compared on the new tank to my original tank was identical in measurement connection and capacity other than the bottom drain port. The process consisted removing the bottom RV liner and roll it back far enough to get access to the tank connections and hardware. Remove cross-member hardware and belly straps on removable cross-member side. Swing the belly straps out of the way(that are still connected to the welded cross member). Photograph all electrical and plumbing connections. Remove those connections. Remove the tank, and then reverse the process. This project was fairly straight forward. *Additional Notes* The tank rests between two cross members. One welded is place the other secured with 2 self tapping screws at either end. On my Cougar Camp Trailer (28RBSWE) My original tank developed a very small rupture while traveling (about an inch at one bottom side corner) so I put a few layers of duct-tape on all the supporting surfaces before I installed the new tank to add a bit of cushion. I also corrected my kinked vent pipe by adding a 90 degree fitting in the mix. The kink wasn't allowing the tank to burp or vent and may have contributed to the rupture going down the road. The job took a bit of time (4-6 hours including a trip to get plumbing reducer fittings) Also it was harder getting the old one out than putting the new one in. I leak tested over night(no leaks) and all level sensors work just fine . Two people for some parts are helpful but not necessary. I ran a fan to speed up drying in the underside so that I would not be trapping moisture in the bottom. Sorry I only have one pic of the process, but it does show the tank connections, one belly strap, and the removable cross member. ... show more

Fit great
Style: Low-Profile Size: 36 Gallon
Fit perfectly in our 2011 camper. Keystone quit making the original water tank. Not too difficult to install, took about 4 hours and only 2 trips to Home Depot Well made & are hoping it lasts for several years

Received the tank without a single problem, inside package it had a certificate with testing. I haven’t had any leaks and been using the tank for about 2 weeks now in a mobile detailing set-up inside a Corolla Hatchback.

Trailer water tank

Built very well. It's an upgrade to any trailer with a junk tank.

Arrived deformed but works fine
Style: Cube Size: 9 Gallon
Seems ok but mine arrived with one side swollen and bowed out. Had to heat it and flatten out the one side before it could be installed. I’ve used this brand for other uses and it’s hit and miss on quality. Some are perfect and others a little flimsy. Best thing I can say is they offer a wide variety of sizes that I always need so happy with them overall. ... show more

Excellent water tank
Style: Cube Size: 9 Gallon
Very happy with my purchase. The tank is sturdy, and the placement of the bungs, allows for a couple different configurations. I would buy this again, and actually did in a larger volume for a different project. Buy with confidence.
