#145 of 192 12V Accessory to trailer by bapennison Dec 17, 2008 (5:38 am)
On my 2008 Sierra 2500 I have located under the hood the wire going to the 12V assessory to provide power to say a RV. I connected the wire to Stud 1 on the fuse block behind fuse 68. There is a 40Amp fuse already in place. My issue is with the mounting stud itself. I have tried several different types of nuts to tighten the wire down with but it is either too small or too big. Does anyone know what is the tread on this mounting bolt is? Replies to this message: cac4 (Dec 22, 2008 6:59 pm)

Replying to: bubby_wubby (Jan 11, 2009 4:08 pm) There are 2 wires by the fuse box that must be connected to the posts on the outside of the fuse box. I went to the dlr they connected the wires for me. That then connects the power to the towing recepticle. Thanks for asking..

Replying to: wcviper (Jul 02, 2008 9:52 pm) I didn't see an answer to your question... Hope you got it resolved by now, but just in case, here is a half-cent worth. On my '98, I added a second battery in parallel (never got around to putting in an isolator) and ran a fused set of wires with Anderson power connectors into the cab to run my FT-8900. My counsel is to make sure that the transmit power requirement doesn't exceed the circuit capacity and use wire heavy enough to handle the current. I just got my 07 2500HD Duramax (new style) three weeks ago and haven't figured out how I am going to handle radio stuff yet. I have wondered about using the trailer plug to re-charge a gel-cell (that I will use operating stand-alone during extended field operations) on the return trip. Another local ham has a similar rig so I will be playing 20 (at least) questions when I get an audience with him. New rig means so many new questions...   73s N7AKJ
#150 of 192 towing capacity by billybob58 Apr 14, 2009 (6:56 pm)
I am looking at a 1988 3500 with a dump box, a 350 engine and only 90,000 original miles. I want to tow a trailer and backhoe with a total weight of 10,000 lbs, can this vehicle legally pull this weight. Replies to this message: davethecarnut (Apr 29, 2009 11:48 pm)
#151 of 192 Which Rear Diff Do I have? 375 or 410 by peltdude Apr 18, 2009 (4:12 pm)
I have a 2003 GMC Sierra SLT 4x4 Ext Cab. I was looking at getting a 30' toy hauler but did not know which rear end I have on my truck. The owners manual states 2 different types. How can I determine which one I have? Replies to this message: grizzly4 (Apr 18, 2009 6:55 pm) davethecarnut (Apr 29, 2009 11:44 pm)

Replying to: peltdude (Apr 18, 2009 4:12 pm) How much does the trailer weigh? The toy haulers can be VERY heavy and a 30' one is probably more than the truck can pull. Replies to this message: davethecarnut (Apr 29, 2009 11:44 pm)

Replying to: grizzly4 (Apr 18, 2009 6:55 pm) If your wondering whether its 3.73 or 4.10 he's definitely got a 3/4 ton which is fine for a 30 ft trailer. If you're not the original owner, did he at least give you the build sheet? That will definitely tell you.
