The $710 Tow Strap Lesson That Pushed Us to Kenwood Dual Band Mobile Radios

The call came at 3:10 PM on a Thursday in March 2025. One of our installers, Marcus, was on the shoulder of I-85 with a customer's Vauxhall Corsa behind his van. The Corsa had the Corsa Sport cat-back exhaust system 21034 we'd installed the week before, and the muffler was hanging at a bad angle. Through the old radio, I heard maybe every third word: '...strap... hook... can't...' Then static.

He told me later that he thought he knew how to tow a car with a truck strap. He didn't. What followed cost us $710 in exhaust repairs, two lost service hours, and a conversation with a customer that I don't want to repeat.

Why we were towing a car with a truck strap in the first place

I'm the procurement manager at a 12-person auto electronics company. I've managed our fleet and equipment budget ($180,000 annually) for six years, negotiated with 30+ vendors, and documented every order in our cost tracking system. I'm the person who tells people to calculate total cost of ownership, not sticker price.

Which makes it painful to admit: I made the exact mistake I warn against.

In late 2024, our vans still had the original radios from 2018. Audio was bad, batteries wouldn't hold a charge, and one unit had already died. A local Kenwood auto group rep came by and quoted a Kenwood dual band mobile radio package at $1,150 per van, installed. That included the radio, antenna, mounting, programming, and a real warranty.

I said no. I found a budget-brand radio for $520 installed. Six vans: the budget option saved us $3,780. My spreadsheet looked great. My gut said something was off, but I didn't put a line item on the spreadsheet for 'gut.' So I signed the purchase order.

The TCO mistake I didn't see

Here's the thing I say at vendor meetings: TCO means unit price plus add-on fees plus time cost plus risk cost plus rework cost. The budget radio quote had fewer line items, not fewer costs.

The same month, we compared three NB-IoT parking sensor companies for our shop lot. One quoted $8,900, another $11,200, and another $14,500. The $8,900 quote looked best until I asked for a detailed breakdown. It didn't include the gateway, mounting hardware, or the first year of data. The $14,500 quote included everything. The $11,200 vendor matched the $14,500 line for line and still came in lower. That was the best TCO.

With the radios, I didn't do that. I just compared unit prices and stopped.

I don't have hard data on how many times the old radios failed in the three months before the tow incident, because we didn't log every missed transmission. What I can say anecdotally is that three different drivers had complained about audio cutting out on the highway. We wrote it off as vibration. It wasn't just vibration.

The day the strap snapped

The Corsa had come in for a routine check after we installed the Corsa Sport cat-back exhaust system 21034. On the way back to the customer, the exhaust hanger broke. Marcus pulled over. He called the shop. The radio faded in and out, and then it went silent.

He should have waited. He didn't.

A truck strap with a ratchet is not a tow strap. A proper tow strap is designed to stretch and absorb shock. A truck strap, the kind we use to secure cargo, is designed to hold loads, not to pull them. Marcus didn't know the difference, and I had never made it a training topic. If you're searching for how to tow a car with a truck strap, the honest answer is: don't. Use factory tow points and a real tow strap, and if you don't have one, call a tow truck.

The strap snapped. The loose end hit the exhaust. The hanger bent, the muffler sagged, and the Corsa Sport cat-back exhaust system 21034 needed more than a quick rehang. The repair invoice was $710. The customer was patient because she had been with us for years. She didn't have to be.

What the cost report finally showed

After we got the car fixed, I went back to the numbers. I didn't like what I found.

The budget radios cost $520 each. The Kenwood dual band mobile radio package was $1,150 each. The difference across six vans was $3,780. That's the number I used to justify the decision.

The number I didn't use was the cost of the failure. The dead radio on the highway contributed to a $710 exhaust repair, a replacement truck strap ($42), two hours of roadside labor (about $220), and a chunk of customer trust that doesn't show up in any accounting system. That's roughly $1,000 in direct costs from one incident. One incident.

I also had to spend another afternoon re-explaining to the team how to tow a car with a truck strap, or more accurately, why truck straps are for securing cargo, not towing. That's time I can't invoice.

Then I pulled the radio failure notes. One unit completely dead. Two more with intermittent audio. Drivers had been avoiding the highway route whenever possible, which meant longer drive times and fewer installs per day. I wish I had tracked that metric more carefully from the start. What I can say anecdotally is that the cheap option stopped being cheap within about sixty days.

Switching to the Kenwood dual band mobile radio

The Kenwood auto group rep didn't say 'I told you so.' He just resubmitted the same quote. The radio side of the package was $760, and the total with installation was $1,150 per van. I approved it for all six vans.

There's something satisfying about hearing the first clear transmission from a van on the highway after the install. The driver's voice came through like he was in the next bay. No static. No dropping. Just a person who could ask a question and get an answer.

The dual-band functionality matters more than I originally thought. It lets our installers talk to each other on a local channel and still reach the shop on a wide-area channel when they're out on a job. The audio fidelity isn't a luxury. It's the difference between hearing 'the strap snapped' and hearing '...strap... snap...'

According to the FCC's licensing pages (fcc.gov), most business and private land mobile radio operations require a license. The dealer handled the paperwork as part of the quote. That was another cost the budget radio ignored: no engineering, no compliance, no one to call when a frequency didn't work.

As of March 2025, the package price was $1,150 per van. Prices change, so verify current quotes before you budget. The point isn't the exact number. It's that the number on the quote isn't the number you'll actually pay over the life of the product.

What I'd do differently

I have mixed feelings about the whole episode. On one hand, the Kenwood units are great and the team is safer. On the other, I hate that a customer's exhaust had to pay for my procurement lesson.

Here's my new rule: for anything where failure means a safety issue, a missed deadline, or a stranded driver, I calculate TCO before comparing unit prices. I ask every vendor for the same line-item breakdown, the same warranty terms, and the same failure history. If a vendor won't give me those, they don't get on the list.

The parking sensor project worked out because I caught the hidden gateway and data fees before signing. The radio project didn't, because I stopped at the sticker price. Both projects taught me the same lesson: the cheapest quote is just a place to start asking questions, not a place to stop.

And if you're ever tempted to ask how to tow a car with a truck strap, call a tow truck. It's cheaper than the alternative.
