XLR Thunderbolt 340 AMP Location of Freshwater Tanks


Does anyone know the location of the freshwater tank on a 2016 XLR Thunderbolt 340AMP? We are getting a ton of sway when loaded with the RZR and heard it may help to fill the freshwater tank if they are located at the front of the camper. When I called XLR the person I spoke to had to physically walk down to the line and find the PAPER drawings from the engineering department because they don't actually computerize any of their plans. She could not find anything that said where they are actually located...

Any help appreciated!

Welcome to the forum its a great place to get your questions answered. Your freshwater tank should be located just above the fresh water tank drain find the drain and you have found the tank.

Tank Location

Starting from Rear of camper
#6-30 Gallon Gas Tank for ATV

#5-20 Gallon Gas Tank Generator

#4-92 Gallon Fresh Water Tank and blue pipe over rear axle there is a cap, and towards rear there is an overflow blue pipe, 12 gallons in your hot water tank.

#3-I'm guessing 41 Gray Water 2 Kitchen Sink

#2-I'm guessing 41 Gray Water 1 Shower & Sink
The spec sheet said 82 gallons total.

#1-32 Gallon Sewer tank
Last but not least is at the front Directly under your toilet.

I also have the same model. I feel this trailer should have been a tri axle. That said upgrade those tires, especially if your hauling a rzr in back. I have put 4 dirt bikes and gear in the back , but no water in the main tank and had no issues. I am pulling with a dually though. I used a 2500 for my first year.
