I purchased a 94'Casita SD 16' last march and it came with a "Budge Tyvek Cover" which i just opened up and put on the trailer....looks to be a pretty decent cover and has elastic all around......well on the tag i found this name "Budge covers" and the one i have is a tyvek Van V-2 Cover and the bottom shows about six inches of the trailer on both sides which is no big deal but it is a very
light and seems to be built pretty good....my 16' is not that high ( it does have a Maxx-Air cover)so if you have say a 17' with higher ceilings i would go for a taller one.....When this one wears out i will buy another one for the price is right $69
