Midland Radio & Auto Supply FAQ: 7 Costly Mistakes I Made So You Don't Have To

I'm not the expert here — I'm just the guy who's made the most mistakes

I've been handling fleet maintenance and shop supply orders for seven years. In that time, I've personally made (and documented) 13 significant mistakes, totaling roughly $3,100 in wasted budget. Now I maintain our team's pre-purchase checklist so nobody else repeats them. Here's what people ask me most — and the stories behind my answers.

What's covered below:

• What to check before bulk-ordering Midland two-way radios
• The most common mistake when installing DS18 Pro TW120 tweeters
• How to tell real microfiber towels from paint-scratching junk
• Whether the Viking midsize battery charger/maintainer is right for fleet use
• Local Discount Tire in Midland, Michigan vs. buying online
• When you actually need an accident lawyer after a fleet incident
• The one "savings" decision I regret the most

1. What should I check before bulk-ordering Midland two-way radios?

In 2019, I ordered 14 Midland handheld/mobile hybrid radios for a 14-truck fleet. I read the spec sheet, tested two units in our warehouse, and clicked "approve." Fast forward to deployment day: 3 of the 14 units couldn't hold a signal on our canyon routes (they were the entry-level handhelds, not enough power). The rush replacement cost us $620 and pushed deployment back four days. Lesson learned: test in the actual field conditions, not just in the warehouse.

Later, we paid roughly a 40% premium for a supplier that promised two-day delivery with a locked-in date. I'll take that premium over another "probably on time" shipping promise (I've seen how that movie ends).

2. What's the most common mistake when installing DS18 Pro TW120 tweeters?

In September 2022, I approved 8 pairs of DS18 Pro TW120 tweeters for four vans. Sounded simple — they're just tweeters, right? But we wired them at the wrong impedance, and two pairs blew their crossovers. That's a $280 parts order plus a day and a half of labor (ugh, again). Lesson: match impedance and power ratings before wiring, not just frequency response on the box.

Honestly, I'm still not 100% sure why some 4-ohm and 8-ohm mixed setups held up while others didn't. My best guess is it comes down to thermal margin in the crossover, but I haven't verified that.

3. How do I tell if microfiber towels will scratch a customer's paint?

In early 2018, we bought 500 "microfiber" towels from an online seller at 30% below our usual cost (too cheap, in hindsight). The water-bead test — drop a bead of water and see if it beads up rather than absorbing — failed on almost every pack. We used them on maybe a dozen vehicles before someone caught the swirl marks at pre-delivery inspection. Total damage: roughly $890 in rework and customer credits.

The checks are simple enough: look at the GSM (under ~300 is usually too thin), do the water-bead test, run your hand across the pile to feel for grittiness, and rub a scrap corner across a mirror — if it leaves a mark, it'll leave a mark on paint.

4. Is the Viking midsize battery charger and maintainer actually right for fleet use?

We've tried six different chargers/maintainers now, including the Viking midsize model. The biggest mistake is getting the battery chemistry and charge rate wrong. The Viking midsize is fine for lead-acid and AGM, but if you connect it to a lithium-based system, or leave it on high-amp mode overnight on an already-charged battery, you're asking for trouble. In 2019, that pattern ruined four batteries for us — roughly $380 straight into the trash.

I'm not 100% sure the maintenance mode on the Viking actually extends battery life any better than cheaper brands. The numbers look promising, but my sample size is pretty small.

5. Should I use local Discount Tire in Midland, Michigan, or buy online?

If you're searching "discount tire Midland Michigan," you're probably weighing a local install against an online tire buy. My take: add up mounting, balancing, and warranty costs, and the online price often stops looking so cheap. In 2021, a Friday afternoon delivery van blew a tire. We ordered a "cheap" tire online ($140 with rush shipping) — it showed up Monday. The local Discount Tire store quoted about $190 but could mount it that same day, install included. We went local. That extra $50 bought back a business day and a guaranteed delivery run.

6. When do I actually need an accident lawyer after a fleet or motorcycle incident?

I've only dealt with one fleet accident claim properly — a van T-boned at an intersection. If you're searching "Midland motorcycle accident lawyer," you're likely dealing with something more complicated than what I've handled. What I can say from my sample of one: document everything immediately. We nearly got burned because we only had a few bad-angle photos. The police report and a dashcam clip are what saved the claim.

My experience is based on roughly 200 fleet orders and that single accident claim. If you're looking at a personal-injury situation, your situation will almost certainly differ from mine.

7. Which "savings" decision do I regret the most?

March 2023. We needed a batch of maintenance supplies by a hard date. One supplier quoted standard shipping (5–7 business days, no charge); the other quoted $260 for guaranteed 2-day, date-locked delivery. I picked the cheaper one. The shipment arrived a day late, and we had to reschedule a $2,400 on-site install and keep two techs idle. That "cheap" option ended up costing us about $580 in idle time.

Looking back, I should have priced the delay risk into the initial decision. But given what I knew then — standard shipping rarely slips — my choice wasn't unreasonable. It was just wrong (unfortunately).
