TL;DR from this thread: So basically the consensus is that for a big Savana, you really have to choose between a high-end custom fit like the Covercraft Custom WeatherShield HP Vehicle Cover or a more mid-range option like the Empire Covers American Armor Van Cover paired with extra straps.

In my experience, safety is the biggest concern with these massive vans because they act like a sail in the wind. If that cover isn't tight, it can actually scratch your paint or, worse, fly off and cause a hazard. I've tried many over the years and honestly, if you want something that won't budge, check out the Seal Skin Supreme Van Cover. It's built for heavy weather and usually runs around $200-$250. It’s got a great multi-layer setup that's surprisingly breathable so you dont get mold. Just make sure you double-check your wheelbase measurements before ordering! Hope this helps!

Honestly, after years of trying cheap covers, you really need a custom-fit option to handle that high roof. For your situation, I would suggest the Covercraft Custom WeatherShield HP Vehicle Cover. I've used mine on a Savana for three seasons now and it's definitely worth the premium price. It's super breathable so you don't get mold, and the fit is perfect around the mirrors. Plus, it's surprisingly lightweight, making it way easier to put on solo!

For your situation, I'd suggest these:

- Empire Covers American Armor Van Cover (~$180). Technical UV-resistant fabric beats cheap polyester.
- Add Gusto Guard High Wind Straps to keep it secure! 🚐

So, if youre looking at this from a DIY protection standpoint - which is basically what we all do when a full garage isnt an option - you really need to prioritize the material specs. From an expert perspective, you want to look at the hydrostatic pressure rating and UV resistance. Most people UNDERESTIMATE how much damage a loose cover does to clear coat during high-wind events. Heres a couple of professional-grade DIY options that havent been mentioned:
* CarCovers.com Platinum Shield Van Cover: This is pretty much the gold standard for high-exposure driveways. It uses a high-denier polyester with a reflective urethane coating that holds up way better against UV degradation than standard fabric.
* California Car Cover Superweave: If you want a custom fit that feels like professional shop gear, this is it. Its made from high-performance synthetic fibers that literally shed water like a duck while remaining totally breathable. Tbh, the biggest thing with these massive Savanas is the installation technique. If you dont use a proper tie-down system - like integrated grommets or a rope lock - the cover will oscillate and act like sandpaper on your paint. Safety first, so always double-check your tension!

Just wanted to say thanks for everyone chiming in. Super helpful discussion.
