The Tiffin service center in Red Bay quoted Walt Sorrells $1,800 to replace a slide-out gear motor he had already pulled out of his coach and set on the picnic table beside him. New motor on the table. Old motor in a shop bag. Walt had driven down from Tuscaloosa to the Tiffin Allegro Rally at Lake Guntersville State Park three days early so he could pick the motor up from the factory parts counter himself. The quote was to bolt the new one in. His wife Doreen was up in the coach with the door open, half a casserole on the counter, listening to the call on speaker. Let me back up. Sandra and I were parked at the Lake Guntersville State Park campground in northeast Alabama, mid-week, the back end of an Allegro Rally tapering down. A loop full of Tiffin Class A coaches, half of them already hitched and rolling, the other half still parked. Tiffin people are friendly. You walk a loop at a Tiffin rally and you will end up with three cups of coffee inside an hour. Walt and Doreen Sorrells had been at the rally since Friday. 2018 Tiffin Allegro Bus, 40-footer, Cummins ISL, full-paint coach, the kind of rig a man buys when he has worked 38 years as a Mercedes-Benz dealership service manager in Birmingham and finally decides he is done being on the wrong end of a labor bill. Walt was 70. Doreen was 68. Their granddaughter Hannah was getting married Saturday at a venue outside Mentone, two hours east on Lookout Mountain. Doreen was making the rehearsal-dinner casseroles in the coach. The rig had to be off the rally site Thursday morning and at the Mentone venue Friday afternoon. Walt had run the master bedroom slide in Wednesday evening to lock down for travel and the slide had gone in 11 inches and stopped. The gear motor was burned. He could hear it stalling against the gear rack. This was not Walt's first slide motor. He had pulled and replaced one in his daughter's coach two years back and he knew the job. The motor sits on the inside of the slide chassis, low and inboard, four bolts hold it to the rack housing. Three of the bolts are accessible from the basement bay. The fourth, the one closest to the cabin wall, sits behind a frame cross-member and a 12-volt wiring trunk. He had driven to Red Bay first thing Thursday morning, an hour each way, walked into the Tiffin parts counter, paid $312 for the new motor, brought it back, and pulled the old one out by lunch. Then he tried to put the new one in. He had a Snap-On 3/8 ratchet with a flex-head and the flex would not clear the wiring trunk. He had a stubby ratchet that he could fit in the gap but could not turn more than a quarter inch per click before the handle hit the cross-member. He had a 6-inch extension with a wobble that walked off the bolt head twice and dropped the socket down into the slide chassis where he had to lay on his back and fish for it. By two in the afternoon he had called the Tiffin service center back. The shop was booked through next Tuesday. They could send a mobile tech Friday morning. $1,800. Friday morning. The wedding was Saturday at four. That was where Walt was when I walked over with a fresh cup of coffee Doreen had handed me on the loop. Picnic table, two motors side by side, a casserole dish steaming in the coach behind him, and a 70-year-old retired Mercedes service manager looking at $1,800 to bolt a motor in he had already paid $312 for, with a granddaughter's wedding 36 hours out and a slide that would not retract for the drive. I told him I had a tool in my rig that might be worth trying. I walked back and got the offset extension wrench out of the tool roll. It is a chain-driven tool. A flat steel bar, just over 15 inches long, with the socket on one line and the handle on another. Pete in Ohio handed me one in 2022 when I could not get a starter bolt off my F-250 behind the manifold. I have carried it every day since. I handed it to Walt. He turned it over once, ran a finger along the offset, and said, you had this all along. We got down in the basement bay together. He slid the offset extension in past the 12-volt trunk and set the socket on the inboard bolt hole on the new motor's flange. He turned the handle. He had earned the turn. About 40 seconds and the bolt was seated. Three more bolts on the accessible side and the motor was in. He wired the leads, climbed up into the coach, hit the slide switch on the panel by the door, and the master bedroom slide retracted clean. All the way in. Then he ran it back out, then in again, watching the gear rack roll smooth. Doreen, in the coach, just kept stirring her casserole. A minute later I heard the slide motor running once more as Walt cycled it for the third time, the way a man does when he is making sure. Let me do the math, because the math is the verdict. The Tiffin service center wanted $1,800, Friday morning. The motor was $312. The tool was $79. $391. The other $1,409 was not the motor. It was the cross-member in front of the inboard bolt. It was the wiring trunk. It was the reach. Here is what I learned on a Thursday afternoon at the back end of an Allegro Rally on the shore of Lake Guntersville. These coaches are not built for the people who own them. They are built for the bay at Red Bay. The one $312 gear motor that can pin a 40-foot Allegro Bus to a rally site sits one bolt's reach behind a frame member where no normal tool will swing. It is not complicated. It is just hard to reach. And hard to reach is a tool problem, not a skill problem. Walt ran a Mercedes service department for 38 years. He has signed off on more buried-bolt labor tickets than most of us will ever read. He was not beat because he did not understand his slide. He was beat because nothing in his basement could come in behind that wiring trunk at the angle the inboard bolt asks for. The time to have this tool is not Thursday afternoon with a wedding casserole on the counter and a Tiffin service writer telling you Friday morning at $1,800. It is the morning before that. Sitting in your basement bay. Waiting. Suddenly you are not paying a mobile tech a four-figure call-out to bolt in a part you already pulled and paid for. Suddenly you are not missing the rehearsal dinner. Suddenly a slide motor burns at a rally, you already know what it is, and you already have the thing that reaches it. The tool is called the Offset Extension Wrench. $79. Works with whatever sockets you already carry in the bay. Ships from the US in 2 to 5 days. 30-day money-back if it doesn't earn its place in your basement. Around a thousand and counting have already taken them up on it. I'm not going to pretend it solves every job. A seized rusted bolt you'll still want to break loose with a breaker bar first. But for the bolt you can see and can't reach, this is the only thing I've ever found that actually works. Walt couldn't reach his inboard slide bolt Thursday afternoon. By three he could. He and Doreen pulled out of the Guntersville campground at first light Friday, made Mentone by lunchtime, and Doreen got her casseroles on the rehearsal table at six. Hannah walked down the aisle Saturday afternoon at four. Walt stood up when she came past his row. He ordered his own offset extension Sunday night from the Allegro Bus, parked in the cousin's driveway in Fort Payne, on Doreen's phone. If you run a Tiffin or any other high-end Class A with slides and gear motors and entry-step motors and basement bolts you can see but can't reach, the day one of them asks you for a tool you don't carry is coming, and the part will be cheap, and the reach is the only thing that will ever cost you. Not because I said so. Because a retired Mercedes service manager and his wife pulled out of a rally site on their own schedule and made a granddaughter's wedding instead of sitting at Guntersville waiting on a mobile tech to bolt in a part they already pulled themselves. Link below if you want one. Safe travels out there. And if you see a gray 38-footer with the awning out at the next Allegro rally, that will be Sandra and me. Walk a coffee over. Sandra says the bolt that holds your slide in is the bolt that holds your weekend together. Put one in your toolbox: https://wildbeartools.com/products/extension-wrench
