If you're going to quote me, don't clip me.
I said "REFIT". Meaning INSTALLED, so you don't have to. With labor, tax, & freight paid.
I suppose the mail order house will install it & be there if the thing leaks? Try calling them if the truck is in the field leaking. I'll show up with a spill kit. They'll UPS a new one to you. Maybe even eat the freight if you wait for 3 day Ground delivery.
