tongue with dual batteries and bike rack

Here is the completed mod.
Diamond plate aluminum installed forward of tub, stainless dog bowl with threaded rod hole the propane bottle in place, I purchased a longer propane hose to accommodate the routing down under the front and back up to the valve.
Twin 6-volt 208 Ah batteries placed in the tub with two extra propane bottles fit snugly between the battery boxes as noted from a previous post.
The bike rack mount works great, I was able to install a small PVC pipe on the mount to hold our jack handle, drilled a hole for a D clip to prevent it from falling out.  
I removed the original 4" PVC fence post and upgraded to a 6" after purchasing a sewer hose set-up with elbow that was a little too snug for the smaller post
