I had a Fortex for my Triton. It did not have the extra front canopy and was a simple enclosed Aronde. I cannot find the original catalogue pdf I saved but I do recall it weighed about 34kg, but cannot remember if this was in the bags or loose. You need to realistically allow 40kg. They are huge.

If you contact F Grunder at info@voortent.net he should be able to give you an exact weight. His English is perfect and on the two occasions I have e-mailed his replies have come back very quickly.

The two awnings you are considering are very different. The Walker a traditional frame shape whilst the Fortex is a barrel design. Each will take a similar time to errect, although I must admit I could set out our Fortex more quickly than previous traditional frame awnings.
The real differences though are in price, availability second hand and footprint. The Fortex as I said above is huge, but until you actually work it out you do not realise how big the difference is. It is twice the size.
Walker 3.6 x 2.4 = 8.6 m2
Fortex 5.7 x 3 = 17.1 m2
I am biased, I've owned two Fortex awnings and if I needed a large awning it would be at the top of my list. Only you can decide if you need something the size of a barn.
