New LC 2003 Owner With Towing Question

[MOMule]

We just bought our first LC, a used 2003 in top condition ... people think it's a 2011 when they first see it. We're delighted with it so far, my hubby even got past the gas consumption issue after a test drive. We live in Indiana so expect it will be a real plus during our lousy winters. Now for the question:

I've read on here about trailer wiring feedback problems with the 2003. I printed a few of those threads to show our RV dealer who did the brake controller, but they want to see a TSB. I've looked for a TSB to show the RV folks, but can't find one that relates to that problem in particular. So far Toyota dealerships have been no help, either. (Big surprise there.)

I suspect these guys think I'm just a silly woman who doesn't know squat, but I don't want to risk blowing electronics the first time we tow our trailer. We've already had the trailer battery run down after sitting connected to the LC's wiring for a few hours, so I'm especially anxious now. Any help would be appreciated. Very much!

Finally, I'm so grateful for all the wisdom here. I've already learned so much and am glad to have a place to ask questions with folks who know this truck the best. The only problem - this site can be addicting.

Here's the full list of TSBs from the FAQs. Not sure what you need is in the list, though.

Too bad your RV dealer won't listen to the wisdom on this board and has to see something "official" from Toyota. Pretty savvy bunch of folks here.

Did you buy the gray 03 from the bloomington toyota dealer??

Thanks, Sandroad ... I did look at these TSBs but couldn't find one that referred to the wiring feedback problem. I've searched all over the web and you guys are the only ones who've mentioned this and told how to fix it. Hubby is anxious to try out the new trailer but I don't want to hit the road until I'm confident we're not going to have an expensive fix later.

Yes, as a matter of fact, we did. Did you check it out, too or just see the listing? There was a guy from Cincinnati sitting in the lot in his old LC waiting to drive it after us. He was rather unhappy when he found it he was too late.
