Be kind and patient. But... I HATE covers. They are expensive (and temporary), hard to put on and take off. AND, the trailer or vehicle needs to be steller clean when put on or all the grit on the trailer (or vehicle) embeds itself in the soft underside of the cover.
I come from a hotrod background where folks spend $$$$$$ on paint jobs. Honestly, we'd rather a vehicle sit outside than have a cover scrub the paint. One little twig or dust bunny can ruin a paint job. A little bit of wind and that cover acts like sandpaper if anything is embedded in the underside.
I understand about HOAs and expense when it comes to building a carport or lean-to (No one has a stronger HOA than where I live). But, I will scrub my trailer (and have for hours) rather than ruin the finish because of a cover. Nothing, absolutely nothing touches the finish of my trailer or any of my vehicles.
I saved money for three years (income tax returns, bottle deposit returns, cash gifts, etc., etc.) to have a 18x25 cover built. AND, if/when I sell my home I can honestly post it having an RV covered space. And the best part is my trailer just gets dusty under there and I can open the door, even if it's downpouring rain and everything stays dry. I've even washed and waxed the trailer under the carport!
So, when you're on your second or third cover... just remember, if you would have saved that money, you too may have built an asset instead of spent the money on an expense.
YMMV
