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.

The polished internal screw on this powered jack ensures supremely quiet operation. Easy-to-access toggle switch and bright, side-mounted LEDs make setup a cinch. Durable, corrosion-resistant jack Features: Electric jack with 12V motor lets you lift and lower your A-frame trailer quickly and easily Sturdy, polished internal screw provides extremely quiet operation Top-mounted toggle switch

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.

Another benefit is that it shuts off automatically before topping or bottoming out, which prevents damage to the gears.

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.

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.

Other types of RV accessories are designed to protect mechanical aspects of your camper. For example, new trailer brakes and torsion axles are necessary if your vehicle breaks down. However, you may also need to get RV leveling blocks to keep your camper from moving under uneven ground. These items are useful for keeping your camper running properly.

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...
