  1. Nice rig towing that 7,000 lb beauty. I have the same rig in Pacific Blue. Two weeks ago got a call from a nearby friend at 5 PM whose Corvette broke down immediately after a fuel stop in Georgia, about 225 miles from home here in Florida. The shifter cable broke when going into gear to leave. Loaded tools and floor jack and hooked up my 23' Continental enclosed car trailer. This was the first time I hauled it with my PB '20 AT4. Hauled many times with my c06 5.3L Silverado, which did the job but struggled. The AT4 pulled it superbly, empty around 3500, ab
  2. Got a call from a friend at 4:30 pm Wednesday that his 2011 Corvette broke down at a gas station in Georgia after his last fill-up for his drive, about 250 miles from home here in eastern/central Florida. He had been up since 2AM driving from MD, and also after getting stuck on Rte 95S for several hours of road construction in NC. I told him I'd rescue him. I own a 2004 20'/24'(OAL) enclosed Continental car trailer. Great trailer with lots of capacity, winch, etc. I hadn't used my AT4 to haul this one before the call. My 2006 Silverado 1500 4x4 5.3L had plenty of pulls but always
  3. Yes the old iron block 5.3L Vortec was ok and a better choice over the base(4.6L iirc?) at the time. I've read about the present aluminum block Ecotec3 5.3L version being more powerful. My '06 was 4WD so it likely dropped the tow capacity down a bit due to added weight . It had the HD Trailer Tow pkg. Not sure if that actually adds weight or not, or is a wash for the tow capacity. I'd imagine the same with the AT4 being 4WD that they drop it down a bit from a 6.2L base rig in 2WD. The 6.2 is likely a bit heavier than the 5.3 but probably not too much. Is yours 4WD? If
  4. It's the AT4... 6.2L gas with 10 speed. Pulls like a dream. Trailer weighs only around 4,000 lbs plus the water tank was full, so maybe 4400 or so, but when we go off fully loaded with stuff it'll likely be around 5k. No Gray or Black water in it when I test drove my setup after they delivered it. The trailer rating for the truck is 9,200 lbs. I have a load leveling hitch setup and set it so the truck is within about 1/4" or so from the unloaded level position. No squatting. IIRC when I first connected up it only squatted about 1 1/2" at the rear bumper which surprised me. After
  5. Ready for some travelling soon. Forest RIver Salem Cruise Lite 17'. Added the GM trailer camera system too. A few camera views here..... Default view from side mirrors https://www.youtube.com/watch?v=zhMS11KDJQU Transparent Trailer Cam view https://www.youtube.com/watch?v=eiTgTIGAqFw
  6. Haven't..... but doesn't mean it hasn't to others. Did you try repeated on-offs and wait to retries? Regardless, you need that update to correct related radio issues so it may be best to have your dealer do it so there's a record of the fault. They can also diagnose the wheel button functions as well, if it persists. Please let us know what happens. Rich
  7. Update... Wednesday I setup an appointment for 1st oil/rotate and to address and record the radio sound issue I had, and the HUD display loss, both of which were only once. A new oddity had been occurring too when XM would just cut out on engine start. It would display "acquiring signal" but never would in known good signal areas. The XM "acquiring signal" fault had continued intermittently over the last week. Continued "resets" by power off/on or engine off/on would not correct. Typically after a few hours of rest and restarts, XM would return.
  8. My 'just acquired 20 AT4 after 3k miles just did that... No radio/GPS lady sound after sub freezing temps Saturday morning. Just started out long drive back south. Disappointed, but..... Then after a while sound returned. Very strange. At first I thought maybe a built in delay due to low temperature but not sensible to engineer that in vehicles that reside in cold climates. It must be a hw or sw fault, albeit intermittent. Then after another stop and restart, the HUD disappeared. Later after another shut down and restart, HUD display reappeared. Drove 1500 m
