Anyone use a removable cover to protect their horse trailer?   Pros, cons, any manfuacturer better than others? 

Our trailer is a gooseneck about 25 ft long end to end.  We only use it on weekends, so it would be covered Monday-Friday.

I realize a structure would be ideal, but we live in a deed restricted development and I currently don't want to spend the $$$ to build it in compliance with the HOA rules and regulations. 

We are in Florida.  Thanks.

Depending on what type of trailer you have, (LQ or not) will determine if using a cover will be worth the effort or not. A LQ with air, vents, solar panels etc, will require a custom made cover. A one piece flat type will quickly wear at any point, where the installed equipment proud of the roofline, will chafe through the material. In addition, the custom fitting will make the installation and removal difficult, usually involving multiple people and ladders.

If you have a smooth roofline, installation and removal are easier, and can usually be managed mostly from the ground. There are several sources of covers. Here are a couple of them:

Our trailers, one with a fiberglass roof and the other aluminum, sit exposed constantly to our various weather changes. Every couple of years they are inspected and the caulking is renewed. They have been trouble free. We have neighbours that used to tarp their recreational trailers. Most of the inexpensive tarps would be shot in a few months, one custom cover came apart at the seams. None bode well for long, whilst exposed to our Fall and Winter winds.

At one time I also considered covers. When faced with the initial cost of a good one, it's relatively short life span and the necessity of two people handling it a couple ofl times a week, it quickly was disregarded. Our ownership maintenance has been greatly reduced by their absence.
