A modernized oil tank would be great. We have older oil trucks from CMW, Magnuson anf I think GHQ had one, but these were all the 60's style with a hose closet rather than the hose spool. We could really use one with a hose spool. These have been around for 30 years and would work with anything from the Athearn Ford C, Mack R, Atlas LNT and upcoming Showcase Internationals.
