They can work, but are a booger to put on. I still REALLY think it is best for those buying a "more expensive coach" to just buy a practical coach and use the savings to get covered storage (if you can). I've seen coaches 30+ years old in immaculate condition from fully enclosed covered storage. Roofs do not leak, bird stuff/bugs do not matter... Only real thing to concern with is freezes and rodents - but for those you simply can leave poison bait all over the enclosed storage - and depending on where you are at in the country you can leave a couple old school light bulbs ON in the coach to avoid freezes (me=Texas and it works).
