While you could possibly run the power from the 7-Way to the jack, it is not ideal and you could overload the circuit. I recommend adding a battery to the trailer and providing a maintenance charge to the battery from the 7-Way. You will connect the 12 volt circuit from the 7-Way trailer connector to the positive battery terminal. The jack will get its power from the trailer battery this way and not from the vehicle 7-Way. Having the wire to provide a maintenance charge will only maintain...

Yes. A 3,000 pound electric jack will work just fine. Based on your trailer weighing 7,500 pounds loaded will equate to your tongue weight between 750-1125 pounds. Although you can choose a 2,500 pound (see link attached) electric jack, I would highly recommend the Stromberg Carlson # JET-3555 (white) or # JET-3755 (black) as they are rated at 3,500 pounds. I think you will really like the price point! I have also included an FAQ for you too.
I went out to the warehouse to look at the Lippert Electric A-Frame Tongue Jack, # LC285318. In order to remove the screws that secure the cover you will need a long and thin phillips head screwdriver. If you don't already have one, you'll want to purchase a Protective Cover, # UF38-944020, to keep your jack dry when you are at the campsite. This will protect the head of the jack and keep the motor protected from the elements.

A trailer tongue jack is designed to lift the front of the trailer, so you first need to know how much this is. The most accurate way to determining trailer tongue weight is to, well, weigh your trailer. Or you can spitball by figuring out what 15% of your trailer's maximum weight is, as tongue weight should be no more than 15% of the weight of your trailer.
Bought one to protect the head unit on boat trailer electric jack. Works great. Bought two more to protect our eBike (pedelec) computers on the handlebars of our bicycles. Fits nicely over the brake handles and the computers to protect them from inclement weather. Our bikes sit on an external bike rack when we travel. I had to take apart the computers and use a hairdryer on them after out last two thousand mile trip. Hope these eliminate having to do that and prevent future damage to the computers. 319085
The etrailer.com Electric Jack w/ Footplate - Drop Leg - A-Frame - 25-1/8" Lift - 3,500 lbs - Black, # EJ-3520-BBX, comes with a 1 year warranty on parts. It is designed to be water resistant with its zinc coating and plastic housing, but you could put a cover on it if you desire like the Ultra-Fab Protective Cover for Electric A-Frame Jacks - Vinyl - 12" x 14-1/2", # UF38-944020, to prolong the life of the jack.

One pretty awesome solution is the Towing Organizer by GR Innovations. This made in the USA organizational solution attaches around your trailer jack (either manual or electric) and gives you a place to hang two safety chains, an emergency brake cable, and an electrical harness. Making everything neat and organized (and making Marshall a very happy camper).

I purchased this cover for my BD500199 electric tongue jack. It fits great, looks good, and stays in place while driving... one bit of advice though: my level blistered, or shattered, I'm assuming from heat. the cover basically rests right on top of the level. I contacted etrailer and they sent me a new level. I have a foam insulator between the level and the cover now. 541015

According to the information I was able to find, the Ultra-Fab Electric A-Frame Jack you referenced, part # UF38-944016 would be a good choice for the Keystone Outback Toy Hauler you mentioned. The jack has a 3500 lb lift capacity, which is plenty for the listed tongue weight of the toy hauler, plus anything stowed on it. Among the many features of this jack, I like the fact that is uses LED lamps for long life as well as the fact that a 9/16 inch socket wrench can be used in an emergency...
Mildew Prevention and Treatment No matter how carefully maintained, every RV cover can be a target for a case of mildew. What causes mildew and what are the most sensible ways to prevent and treat it? Mildew is a form of fungus present everywhere in the world. It is a primitive plant form that feeds on other plants and produces microscopic, seed-like spores that float freely. It takes dark, damp conditions to encourage their growth. Synthetic cover fabrics do not support the growth of mildew. Natural cover fabrics (those containing cotton) can support the growth of mildew, but such fabrics are treated with mildew inhibitors that will, with proper care, typically outlast the warranty period of the cover. However, dirt, pollen and other environmental particles that embed between the fbers of any cover fabric are gourmet fare for mildew and therefore, no RV cover fabric can prevent mildew from growing. Most remedies rely on sodium hypochlorite (household bleach) to remove mildew. A good, strong, all-around solution is ½ cup household bleach per gallon of water. Do not use liquid detergents in combination with bleaches. Scrub the affected surfaces with a soft brush, using rubber gloves and eye protection. Rinse thoroughly. For cleaning our covers, we highly recommend 303 Marine & Recreation Multi-Surface Cleaner which is safe and effective. Be aware that repeated cleanings can diminish the water repellency of the canvas. To restore water repellency to factory-new levels, we highly recommend 303 Marine & Recreation Fabric Guard. Remember that anything used to kill or remove mildew will wash or wear away over time, so be prepared for repeated treatments as part of your maintenance routine.
The best jack is extremely relative, and is dependent on many factors. The Etrailer.com Electric Jack w/ Footplate - A-Frame - 25-1/8" Lift - 3.5K - Black # EJ-3520-BBX will work very well for your 3500 lb dry weight travel trailer and has an excellent price point for this type of jack. It includes a 5-5/8 inch inch drop leg to allow faster extension and retraction and utilizes 2 switches for function; one for power and one for raising or lowering the jack. It also has LED lights to...
Ball Screw Drive MechanismThe ball screw drive uses ball bearings (rotational friction) that offers superior performance over metal-on-metal gear mechanisms (sliding friction) used by other manufacturers. Ball screw drives use less power, have better lifting capability, provide quieter operation, and offer additional benefits.Ball Screw Drive Mechanism

If the a-frame jack you have on your trailer failed I recommend getting a stronger jack for your 2013 Springdale trailer. I recommend the Bulldog Powered Drive Trailer Jack, part # BD500199. This has a 4,000-lb capacity and a total travel of 22-inches. You may also want to keep a cover on the jack when it is not being used if you do not already have one. I recommend a cover like part # UF38-944020. This weatherproof cover has a drawstring that helps hold it secure to the jack.
Then inside, we're going to have a nice soft material. Even if the wind's blowing this around a little bit or something like that we're not going to have to worry about any abrasion on our jack. The way it works is the simple drawstring here is going to pull down and secure around the outer tube of our jack. We'll just slide it over the top just like this, then cinch to close. This is going to protect not only the jack motor body itself but also our switches and out light from any kind of discoloration from UV fading. Also, it's going to protect it from the rain, the snow, dirt, debris.
Eliminate the physical exertion commonly associated with lifting and lowering a trailer when you use a Stromberg Carlson 3500 lb. Electric Tongue Jack. It does the heavy lifting for you, and has lots of other features as well. For example, the trailer tongue electric jack has equalizing bars that are easy to set, so you get better results, and two separate LED night lights that provide both added safety and additional illumination. The leg extends up to 23; and although it is heavy and durable, it's also surprisingly lightweight and easy to store.
