If the motor on the electric tongue jack on your 2017 Forest River Flagstaff Super Lite tandem-axle travel trailer operates but the jack does not raise or lower the trailer tongue then you might have over-extended the jack and damaged the internal screw mechanism. You might try the manual crank handle to see if the jack extends or retracts when manually operated. If not, then your jack needs to be rebuilt or replaced.

Some jacks like the Stromberg Carlson # SC63VR have a built-in auto-stop feature that prevents damage to the gears from over-extension. This jack has 4500 pounds of lifting capacity

Any weight-bearing item - a jack or a winch - will work better and last longer if operated below its maximum rated capacity. If you do prefer a new jack instead of repairing your original unit then the Husky would be an excellent choice.

It is likely that the interior gears have stripped when the jack over-extended. If you have the manual crank that should have came with the jack, use it by removing the rubber plug at the top of the jack, insert the crank and fit it to the override…

It sounds like the switch in the jack is bad and should be replaced. Typically when an electric jack will go one direction but not the other its because the switch is broken. You might try checking all the fuses on the jack also. Since your trailer…

You are going to have to remove your current A-frame jack and replace it with one that does have a motor as there isn't a way to add motors to jacks that don't currently have them. I think the best value for an A-frame tongue jack is the…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Thanks for providing that information it really makes this simple. To find the right Gen-Y we need to calculate your tongue weight using the formula GVWR x 0.22 = TW. The Z2900 has a GVWR of 14,495 lbs so the TW is 3,189 lbs. Based on this…
