Jack Cover, (John Higson Cover, Jr.), American physicist and inventor (born April 6, 1920, New York, N.Y.—died Feb. 7, 2009, Mission Viejo, Calif.), spent most of his career in aerospace but became famous in the mid-1970s for inventing the TASER, a handheld weapon that fires darts attached to insulated wires to deliver debilitating electric shocks at ranges of up to several metres. Cover’s goal was to devise a nonlethal means of stopping violent acts, such as riots and hijackings. Though the TASER was initially classified as a firearm because the darts were propelled by gunpowder, in 1993 Cover used compressed nitrogen to activate the darts; the modification allowed the public to purchase his invention. The TASER name (a registered trademark) was a modified acronym from the title of one of Cover’s favourite childhood books: Tom Swift and His Electric Rifle.
Those who are interested in buying items like these have many different types available for their needs. For example, a trailer fender is necessary for protecting your RV from impact damage. They can fit where old ones were and fix any auto body concerns from which your vehicle suffered. More specific types include RV awnings that provide you with a comfortable place to sit during rainy weather.

After what seemed like a hundred cranks, your trailer is lifted enough to attach the hitch to your truck, but your arm feels ready to fall off. An electric trailer jack can save your arm by lifting your trailer hitch with just the touch of a button. Most electric jacks use 12V power, so you can hook them up to a battery while you are out on the go and not worry about finding an outlet. Most models also include a manual jack handle as well so you can still lift the trailer, even if your battery runs out of power. The Barker electric trailer jack is a commonly found option, and the VIP 3500 can handle most campers and travel trailers, as it is rated to lift up to 3,500 lbs. This model lifts trailers up to 18 inches, so you can easily attach your trailer to your truck or SUV. There are many electric trailer jack options available with many lift capabilities, and with the large inventory available on eBay, you can lift your trailer with the touch of a button in no time.

Ever wonder what to do with your trailer safety chains, trailer emergency brake cable, and electrical connector when your trailer isn't hooked up to your tow vehicle? Hate to see these items just lying on the ground? Well if you are anything like Camp Addict co-founder Marshall, trying to find a good place to store these items drives you insane! (Camp Addict co-founder Kelly could care less about these details. 😂)
So every time she has had to hitch up, which is often, raising  and lowering her jack has darn near thrown her back back out. To make matters worse, with an e2 weight distribution hitch she loathes, she has to (usually) RAISE the jack up to get the coupler high enough to clear the ball, LOWER it down onto the ball. Then she has to again RAISE the hitch way up, literally lifting the back of the truck, so she can get her weight distribution bars high enough to install them. Finally, she has to LOWER it back down until the jack foot is all the way up. That's a lot of cranking and it makes Kelly cranky. (Sorry. Couldn't resist.)
OK, so you have your trailer tongue weight (or a rough idea what it is). What next? If you have a weight distribution hitch that uses spring arms, it's very likely that you will need to raise both the front of the trailer and the rear of your tow vehicle in order to be able to get the spring arms onto their brackets. So not only is the tongue jack lifting the weight of the front of your trailer, it is also picking up the rear of your tow vehicle. 😳

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...

I have used this cover to cover the tow jack on my trailer which has been parked up on the drive of my beach house for the last 12+ months. It has therefore been subjected to a marine type environment which plays havoc with house door fittings etc. The cover has survived intact and is now still in an "as new" condition. I am very pleased with this purchase and highly recommend it. 424779
