Thanks guys.........i forgot just how lucky I am. I'm retired military and we have a auto hobby shop on almost every base. I just pull up on the rack, drain, change filter, refill, and they get the oil. Parts plus about $8-10 rack time and I'm out. I even installed my wireless air bag system at teh hobby shop. That air bag system works like a naked lady on a horney inmate!!! BBTank

The trailer should be grounded on itself and not need a seperate ground from the plug to the frame ofg the traoler, it should be grounded already from the trailer to the plug itself. Make a jumper wire with a 5A fuse in it. Jump from the battery to each of the light terminals, that should "light up" all the lights, one circuit at a time.And that's my 2 cents worth. BBTank

I was a RV tech at Beaudry RV, in Tucson. I've gone back to work for the Air Force now tho'. The "female" part that I'm talking about it the female portion that's on the truck. You can buy the female part and put alligator clips on any/all wires to test different lights, wires, connections, etc. A jumper is just that to me, not making sense to you, in my terminology. Jumper is just a piece of wire, length is up to you, that has alligator clips on each end. I have a few different lengths for different jobs. Now the fuse thing, it's ok, if the fuse reaches across, which I'm guessing oit does, since you're doing it. Like previously stated, test the truck plug to see what kind of power you have there. That's the first place to start. After finding out that, it may lead you to what happened to the trailer. I also have a PowerProbe from one of the tool trucks. I think you can find one at a good auto parts store. A powerProbe is a kinda test light with a probe out of the handle and 3 wires coming out of it. The 2 wires in the long sheath, are for pos. and neg. battery connections. This HAS to be connected to the battery of whatever vehicle you're gonna test. The shorter black wire with an alligator clip is for a local ground that you may need to add. The PowerProbe has a 3 position switch on it. The middle is the test mode, a light shows red or green for + and -. The switch can be rocked forward or backward. One way will add + and the other will add - to test a particular circuit. That tells you what circuit has ground, power, or if its just plain AFU. I hope I haven't insulted anyone's intelligence, I was just wanting to be very simple, because I can get too technical sometimes. I hope I helped, and not confused, BBTank

Are you guys using "jumpers" or a female plug end? If you're using a jumper wire, you could be touching another connection causing it to not light up. I'm a RV tech, and I have a female 7 pin connector that I put alligator clips on the ends of the 7 wires. All you have to do then is clip what you want together and viola, it works, and it tests any circuit in the running/brake lights, and the electric brakes too. If this ain't what you're doing, I'm stumped since I'm a few miles away. Does it work when plugged into the truck, towing? BBTank

I'm not sure, but I think I remember my 08 2500HD diesel 4X2 weighing in around 7400 lbs. All the literature I have on my 06 GearBox 375FS says 10,500 empty. With 125 gals of water, food, BEER, personal items, 13,500 lbs. So 20,900 lbs. total? I'm gonna have to pull it to work one day, we have a free scale right by the entry gate. I still have no toys to put in it yet! (I've been looking hard)

I just (Jun 09) bought a Fleetwood GearBox, 375FS, 39' toy hauler. Don't have any toys in it yet, but looking for a sand car now. From the cabinet to the back door is right at 20 ft., so I don't think I'll have to worry about the length of the car. We're USAF retired, in our early 50's and this hauler fits our needs very well. We take it to the drag strip and entertain friends, BBQ, and drink too much. We have room for coolers, BBQ's, chairs, and all the other "stuff" we need to party well and would still have room for a car if we folded the furniture out of the way. We go to the lake and have too much fun there too. When we find that sand car, we'll hit the dunes and party big time there too. I wanted something this big to have the room WE needed. You might answer the questions that these folks have asked, and find out you need a 25' model. Whatever you do, don't settle. It took me over 6 months to find mine, and I had to drive from Tucson to Phoenix, AZ to look at, and buy it.
