Had a local garden place that represented a manufacturer that was 300 miles away. They sent a crew with 3-4 covers to be installed locally. I had a 24'w x 14' x 34' with additional 6' drop siding in about 3 hours. I ordered with maximum bracing that included diagonal bracing at every vertical to the roof and 4 at ground to vertical on each side. Rated for 120 mph. I should have ordered 6' longer. I recommend that you go at least 6' longer than camper. Material is Galvalume with 25 year warranty and don't believe that the standard material is aluminum but it may be available as an option.
With the maximum bracing, I found that most companies will charge about $100/foot. Paid a deposit and final payment after completion. If there are any issues with installation, I suggest you withhold some money as an incentive to come back to complete it. I poured my own slab and had it mounted 6" inside edge to ensure that slab did not crack when they bolted it on. They can install in soil with augers screwed into ground.
It sure is huge once installed. If I had it to do over, I would have had it installed to cover camper and wide enough to open sides and another next to it that was lower to park my truck.
I see you are on Texas. Superior Carport installed mine and is the manufacturer /installer from Victoria. I highly recommend them.
