Hi..Quick Questions

[Alt-F4]

Hi. all!
I'm a long time Lurker turn Member, finally.heh
Nice site!
I should be picking up my 05 SUT on Monday.
I have used the search feature and also called this website's store and my dealer (who said they were a Gobi dealer)about Gobi racks for this truck.
I tried to call Gobi direct but the phone number was not good on the sight.

My Questions are.

From what I have read on this and a couple other forums is that Gobi racks are the Best for the H2 SUT.. Is this true? If not what other racks are available, besides custom?

What do you think is the best package deal I could get buying the SUT Roof Rack for spare tire /w sun roof and the SUT Bed Rack as a one shot deal?

Also..

Does anyone know what the differance is between the GHSUTTSR2, and the GHSUTTSR4?These are the model numbers from Gobi website. I read all the info and looked at the spec's.. All that seamed to be differant was the weight. Is one heavy duty and one light weight?

Does the {4"} and {2"} mounting brackets change the height of the system? or is that the size of the mounting brackets at connection to the truck?

I hope I don't sound Noob .. But I am to these trucks..I have used my resorces and not found all the answers to the rack questions.

Thats for any and all resopnce..
