If a trailer didn't have a trailer jack, this means of transport would be pretty much useless – unless you are strong enough to lift it by hands or hitch (unhitch) a tow vehicle somehow else. Jacks can be manual and electric. With the help of an electric jack, you can hitch up substantially easier than with the manual unit, since a manual jack requires the application of physical force. Anyway, whatever the trailer jack you have, this part has to be completely workable and sufficiently reliable to prevent troubles during a journey under various conditions.

When going camping in your RV, there are many accessories that you can add to make your experience more enjoyable. These accessories and parts include items as diverse as leveling blocks, chocks, air conditioners, towing items, and even awnings. When considering awnings and other RV parts, it is important to understand the benefits they provide you.
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.

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...

There are several places water can get into any given jack. Water should be able to drain out though. If the exit points which would be at the lowest point are clogged then the water would not be able to exit. You could use a jack cover like # UF38-944020 for future use. There is no telling how much damage is really done. If there is enough corrosion then something inside could be structurally compromised and fail when you have weight on the jack. I would not be comfortable offering...

It sounds like there may be a short in your Bulldog jack which could have been caused by excessive moisture from the rain. Also I recommend checking the wiring from the jack to the ground and power sources. The jack grounds through the mounting hardware so you may need to temporarily remove the jack (be sure to support the trailer another way) and sand away any corrosion. Also check for corrosion or damage to the power wire and where it connects to the battery. The light switch...

Mr. Cover named his invention as a tribute to another inspiration, the Tom Swift science fiction novels he read as a child, one of which was “Tom Swift and His Electric Rifle.” He created an acronym from “Thomas Swift Electric Rifle,” adding the “A,” he explained to The Washington Post in 1976, “because we got tired of answering the phone ‘T.S.E.R.’ ”

The former, obviously, and through personal experience, is much harder to use than the latter. However, the primary benefit of the manual jack is that it COULD be less prone to breaking since it is a simpler device. The electric trailer jack could fail electrically or mechanically. The electric trailer jack will also require installation or some know-how as far as wiring goes.
