Best place to buy A&E awning tube with fabric?

I also found PPL Motorhomes had best prices on A&E Awnings when I replaced mine last spring. Was as cheap as my repair shop could get it. Shipping was $120 for a complete 12' awning including arms. I would guess the 18' tube w/fabric would be as expensive, possibly more to ship.

Question is, would the complete tube/fabric with shipping & installation be comparable to fabric only with shipping & installation??
