With the right tools, a big caveat, setting up a dish does only take a few minutes depending on the tripod setup and the tie down system. I use two 5 gallons buckets of water and it takes a few minutes to fill them.
It is no harder to aim a DPP 1000 than a DPP 500. If the Skew is set, once you hit 119 with either dish, you are done.
We started with a Winegard AS-2003, a old single LNBF automatic roof dish. Once we encountered the issues of a single LNBF, we started to use a ground tripod and we did for almost 6 years until we got a Winegard Trav'ler roof dish. We still carry the tripod for the times that trees are a a problem.
A good adjustable leg tripod and a good meter with cost almost $200, about half the cost of the Tailgater so I would recommend the ground tripod, not for cost, but the full triple LNBF functionality and the greater reception capabilities because of the larger dish surface.
As for the cost/reliability factor of the Tailgater. Comparing it to a consumer product where hundreds of thousands units are made, like a wash machine, just doesn't compare to the limited manufacturing of automatic RV dishes where the productions might, might, hit into the thousands. If the automatic satellite dish manufactures could count on hundreds of thousands of units, the cost factor would radically drop and the savings could be put into beefed up components.
