I tried email, but didn't get a response. I'll try here as well. I saw on your site you plan to have a rear bumper available. When do you anticipate it being ready? Do you have an estimated price? Will the bumper be available standalone, or will it only be available with a tire carrier? Will the bumper bolt through where spare stores underneath like the Calmini bumper, or can you leave the spare underneath with the bumper attached? Thanks for any information you can provide.
