Can You Reverse With The Curt Trunnion Style Weight Distribution System Part # 17300  

Question:

Hi Conner, This summer I purchased a Sonic travel trailer. When we made our shake-down trip, we discovered that having a portable tote tank for extended trips is going to be pretty much a necessity. I was looking at the Barker tanks which look to be well made and had initially selected their 32 gallon tank: However, I find that the Sonic's sewer drain is only about 10" above ground level. This means that I need a tote tank with a tank fill opening height of less than 10". I'm not having much luck in finding such a low silhouette tank. The only low silhouette tank I've found is the 15 gallon tent camper tote-along which measures 7.75" high: This probably meets the low profile criteria I need, but it is a light duty tank that would not hold up to being towed by my truck to a dump station. It also holds less than half the capacity of the Sonic holding tanks. I would like a towable tank with a larger capacity, but obviously can't use a tank with a 11" (or greater) tank height. Do you know of any other options?

Generally speaking, it is recommend that you remove the spring bars from a weight distribution system such as the Curt Trunnion Style Weight Distribution System part # 17300 while in reverse. This is due to the fact the the spring bars will not have enough room to pivot in the head while turning in reverse.

However, this will only occur while reversing with the trailer at an angle. As long as you remain in a straight line, you will not need to remove the spring bars in order to reverse the vehicle and trailer.

In regards to the transmission temperature while towing, it is also a good idea to add a supplemental cooler. I cannot say for certain as to how high the temperature will rise however, as these vehicle were not necessarily built for towing, it will be a good idea for you to install one. The best transmission cooler for you to use will be the largest one is the available space you have between the radiator and grill. For your 2015 Ford Edge, I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13503 as this will be an excellent option for you to consider.

Should you decide to use a different transmission cooler, I have attached a list to all of our cooler options.

Although the drain tube for your RV's waste system may only be 10" off of the ground, the storage tanks that this drain tube is connected to will usually be about 5"- 6" higher than the drain tube. Therefore, gravity will help push the wastewater through the drain and into the portable tank. As long as the wastewater storage tanks are above the portable tank then the system will drain properly. When you are finished draining the system you will want to detach the RV side of the hose first and walk the tube to drain any water stuck inside. For a portable tank I recommend using the Tote-N-Stor Portable RV Wastewater Tank w/ Hose Accessories part # TNS25609. If there is a bayonet fitting on your RV then you will also want to use the Valterra Tote Tank Hose w/ 3" Bayonet Fittings part # D04-0111 to connect the RV's waste system to the portable wastewater tank. This wastewater tank has a 32 gallon capacity in addition to possessing two wheels and a hitch ball loop to allow for your vehicle to pull the tank to the dump station. There is also a top inlet opening to vent the tank for quicker filling or draining. I have attached a review video of the tank and hose for you.
