Metal carport for FT RVer -Need advice

My shade structure is not welded, its all bolted together from 10 ft length galvanize fence post from Lowes, they slip together and than I drilled and put bolts through to hold it all together, its doubled post on each leg for more strength, it has held up fine here with the high winds we also have here in Vegas, its been up now 18 months, the fabric is high quality sun screen for farm use, it has a 7 year warranty and if it gets a hole it wont run, I am using 80 percent sun block, you do not want more than that or it will catch to much wind and could be a problem, it stays cool in RV even with one AC running during the summer.

Your price above of around $3000 seems to low, the RV carports around here 18 x 38 ft with a height of 14 ft was around $7000 installed, I built mine for around $2500.
