I read that the shipping weight was 337 pounds, that was by just doing a google search so dont know if thats correct or not.
What would WORRY me he most about shipping it across the US would be how fragile the RSM is.
If it breaks or cracks during shipping, it's pretty much worthless upon arrival. Who takes the loss? I've read about a couple of tanks being damaged during shipping. Too scary for me to think about..... For both the buyer & the seller.
Mine arrived fine, with amazing delivery speed (less than 5 business days)....but it was shipped direct from Red Sea & they guaranteed it to arrive in new condition.
