I love my RT-1250, no regrets on the pit whatsoever, but you might want to skip the factory cover. The RecTeq cover, at least on the RT-700/RT-1250, is so tight that it tends to tear on the edges of the side shelf. Mine tore after less than a week. RecTeq support is great - they immediately shipped me out a replacement, but I'm sure the replacement will be the same.
RecTeq did point me to a YouTube video on removing and putting on the cover. I was pretty much doing it the same way, but unfortunately the way they show to remove it over the side shelf doesn't work for me without it snagging on the side shelf.
If anyone is reading this while planning on purchasing a RecTeq, you might want to consider a cheaper, generic cover. I had read this advice prior to my purchase, but I didn't heed it - I wish I had! A lot of people have had the same issue, so hopefully this saves someone else the same trouble, and perhaps RecTeq will improve the cover design.
