You may want to throw your tent in your car just in case we set this all up for you and we find out that you are to tall for my rig, although the manufactures website claims it creates a bed surface of 7 ft. 2 in. L x 5 ft. W and if I recall you were tall but not 7 ft. tall. I always feel like this model is a little big for me and I am 5 ft. 8 in. tall. so I think it will be fine for you.
As for as the suspension goes I should have everything we need once my whoopie sling arrives in the mail. Ordered them last week so I am hoping they will arrive this week and thanks to Hairbear's gift exchange on the last camp-out I now have the toggles needed to hold it to the tree straps.
I will give you an update after I set everything up this evening just to be sure that I am not missing anything.
