Optimum Fleet Buyer FAQ: Step Side Bed Panels, Hand Soap on Car Paint, and Clay Bar Spray

Quick background: I'm the office administrator for a 34-person logistics company. I manage all the fleet maintenance and vehicle accessory ordering—roughly $130,000 a year across nine vendors. I report to both operations and finance, so I see every purchase twice: once when I approve it, again when accounting wants to know why the final invoice doesn't match the P.O. That's why I stopped comparing sticker prices and started comparing total cost of ownership (TCO).

Here's what this covers:

• Where to order RV and truck parts when you need actual support (including Optimum RV Spartanburg and Optimum RV Pottstown)
• What to check before buying a step side bed panel
• Whether hand soap on car paint is ever okay
• What spray to use with a clay bar
• Why the cheapest quote usually isn't
• The hidden costs that turn small orders into big headaches

Take it from someone who paid $95 freight on a $180 part.

1. Where Should I Order RV and Truck Parts for a Fleet?

If you're like me, you don't want a vendor that disappears after the sale. I've ordered from both Optimum RV Spartanburg and Optimum RV Pottstown, and the reason I keep them in my system is simple: they have physical locations behind their orders. When a part is wrong, I don't fight a chatbot. I call a branch manager and talk to a person.

That's a total cost thing. The cheapest part in the world isn't cheap if the supplier can't answer a fitment question until tomorrow. We run 14 vehicles out of three locations, so downtime matters. Plus, Optimum's catalog covers automotive, RV, towing, and care products, which means I can put a step side bed panel and a clay bar kit on the same purchase order. Fewer orders, fewer freight charges, less paperwork for my accounting team. It also gives us a local return option for bulky items, which can be the difference between a $30 problem and a $90 problem.

2. What Should I Check Before Buying a Step Side Bed Panel?

The question everyone asks is “how much?” The question they should ask is “will this fit without modification?” A step side bed panel is the exterior body panel on the side of a stepside pickup bed, usually the section between the cab and the rear wheel opening. It's not like ordering a wiper blade.

Here's what I check now:

• Cab type and bed length
• Driver side versus passenger side
• Whether brackets, inner structure, and hardware are included
• Material and finish (bare steel, primed, painted)
• Restocking fee on fitment returns

Looking back, I should have measured the mounting points before ordering a “universal fit” panel. At the time, the price was 30% lower than any other quote. It didn't fit. Return shipping ate the savings, and the truck was down for a day. I planned around total cost, not sticker price. These panels aren't something you want to guess on, especially for a vehicle that has to work tomorrow morning.

3. Can I Use Hand Soap to Wash a Car?

Short answer: don't. I know it's tempting when the wash bay runs out of car wash soap and you've got a white fleet truck that looks like it drove through a dust storm. Hand soap isn't pH-balanced for paint. It strips wax and can leave a film that shows up as streaks on darker colors. Dish soap is worse—it's a degreaser, so it's useful for stripping old sealant and bad for routine maintenance.

If you're in a pinch, use the mildest liquid hand soap you can find and follow with a quick detailer. But here's the cost angle: stripping your sealant means more waxing and more labor later. A $6 bottle of car wash soap is cheap insurance. I keep three in the maintenance closet now. If you're managing a fleet, put it on the checklist: car wash soap, microfiber towels, clay kit for detail days. The products are cheap; paint correction isn't.

4. What Spray Should I Use With a Clay Bar?

Use a clay lubricant or a dedicated quick detailer spray. Not plain water. Clay needs enough slickness to glide over paint and pick up contaminants; without it, clay drags and leaves micro-marring. Then you're looking at machine polishing to fix what you caused.

Some people use car shampoo suds as clay lube, and I get why. But a proper clay spray is cheap and made for the job. A clay bar kit with spray runs about $15-35, and a standalone detail spray is around $8-15 (based on listings I pulled from major auto supply sites in March 2025; verify current pricing). One polish after a marred panel costs way more than that. So “save money with soapy water” wasn't a trade I was willing to make. And if you're using a clay bar for the first time, work in small sections and keep the surface wet. A dry clay bar is basically sandpaper.

5. Why Did My “Cheapest” Supplier End Up Costing More?

In 2022, I found a step side bed panel at a great price—about $180, which was $70 under our regular supplier. Then came freight ($95), no mounting hardware (surprise, surprise), and a return policy with a 20% restocking fee. By the time the panel didn't fit, I'd spent the savings and then some. That was the order that turned me into a total cost person.

Now I compare quotes on four things:

1. Delivered price, not unit price
2. Whether hardware and instructions are included
3. How returns are handled
4. How fast the vendor answers when something's wrong

If you've ever had a part arrive damaged, you know that sinking feeling. The vendor who can't provide proper invoicing cost us $2,400 in rejected expenses once. That's not a pricing problem—it's a process problem. In our 2024 vendor consolidation, I cut my vendor list from 11 to 8, and average order cost went down because I bundled more shipments. I also add a line item in my P.O. notes for “fitment confirmation” on any body panel. It sounds excessive, but it forces someone to check the vehicle's cab configuration before I commit.

6. What Should a B2B Buyer Ask Before Ordering Vehicle Accessories Online?

When I need a part for a fleet vehicle, I'd rather order from a supplier with a real storefront. The Optimum RV Spartanburg branch is a good example: I can confirm stock, ask a fitment question, and get a person on the phone after the sale. The Optimum RV Pottstown location handles a lot of our drop-ship orders and has been just as reliable with invoicing. That matters when finance wants backup paperwork.

Pure online sellers have their place, but for me the best option is the one that doesn't come with a two-hour hold or a “we'll create a return label in 3-5 business days”. When I consolidated vendors, I kept only suppliers who could provide clean invoices, correct part numbers, and a return process that doesn't require four forms. That's the real total cost. If a supplier can't give you those basics, the low price isn't real—you just haven't paid the hidden cost yet.
