In my experience, if you're worried about the $500-$700 range but want maximum protection, you should look into a hybrid approach. A few years back, I bought a truck for heavy hauling and made the mistake of going cheap with a DIY kit—it literally flaked off under my engine hoist.

For your Silverado, I'd suggest the BedRug Classic Bed Liner BRY19SBK if you want that padded feel without the moisture trap issues of plastic drop-ins. It's made of polypropylene (basically plastic) so it won't rot or mold, and it's way easier on the knees. However, since you're hauling firewood and heavy gear, my top pick for durability-on-a-budget is the DEE ZEE DZ16291 Heavy Duty Bed Mat. It’s thick rubber that prevents dents better than any spray-on can.

TL;DR: If you want to stay under budget, get a professional base spray then toss in a WeatherTech 3L021 TechLiner Tailgate Mat for extra impact protection. It's the best way to prevent those deep gouges!

Seconding the recommendation above. I totally agree that staying away from DIY is the best move for safety and long-term value! Honestly, if you're hauling heavy equipment, you really want something that can absorb impacts without cracking.

I've been super happy with the DualLiner Bed Liner for 2023 Chevy Silverado 1500 5.8ft Bed. It's a hybrid system that uses hard plastic sidewalls to prevent dents but includes a thick rubber mat for the floor. Since you're worried about moisture, it's actually designed to drain water away so it doesn't sit against the paint like old-school drop-ins. Plus, it's right in your $500 price range and way easier to install than a spray-on. No complaints here so far! Hope this helps!

Hey! Congrats on the new truck! Honestly, for your situation, I would suggest going with a professional spray-on liner. Avoid the DIY kits at all costs—I tried a roll-on brand once on an older truck and it peeled like a bad sunburn after just one summer of hauling rocks. It's really not worth the hassle if you want it to last the life of the truck.

I’ve had the Line-X Premium Bedliner on my Silverado for about three years now and I’m seriously happy with it. Since you mentioned rain and humidity, a spray-on is the way to go because it bonds directly to the metal. There's no gap for moisture to hide, unlike those drop-ins which definitely can rub the paint raw and lead to rust issues down the line. I use mine for firewood and heavy gear too, and it’s taken some massive hits without a single dent.

If you're worried about the surface being too hard or stuff sliding around, you could always toss a BedRug Classic Bed Mat on top of the spray-on later. That's what a buddy of mine does for his outdoor equipment. But for pure durability? Go with the Rhino Liner TuffGrip or Line-X. You’ll probably spend right around $600-$700 depending on your local shop, but the peace of mind is totally worth it. Good luck with the 2023, it's a great rig!

Seconding the recommendation above. After 15 years with trucks, I've seen DIY kits fail every single time. Honestly, if you're hauling heavy equipment, you need high-pressure application for a real chemical bond. Since you mentioned moisture, check out Line-X Premium Bedliner—the UV coating prevents it from turning chalky. FWIW, if you're worried about dents from firewood, throwing a Dee Zee DZ16202 Heavy Duty Bed Mat over a spray-on is the ultimate bulletproof setup. Worth every penny, imho!
