tanker trailer id

hey guys where would i find the id plate on a tandem axel fuel tanker?

Probably right side mid to front section of the trailer. It's probably the M131 series. DOes it have tandem axles with 5 ton rims?

yes 10 bolt budds and 11/20's

Sure sounds like the M131A5 or the such. Pretty unique trailers from what I've seen.

got a chance to look at trailer again today while working. it's a 131A4 5000 gal. with what looks like all equipment included minus large hoses and spare tire. to bad it has air over hyd brakes. oh well cool piece of equipment just the same. won't know for a few days wether or not it's added to the toy box. it was mfg by city tank corp. culpeper VA.

any ideas what this M131A4 would weigh ? i am not to good with going though the manuals. even a close guess would work.

Dave, I have this manual, which shows "Standard Characteristics" for MV's (TB 55-46-1). Never had a reason to use it before and it lists the M131A4 as having the following dimensions/weight:
374(L) x 97(W) x 108(H) and 14,000 lb.

thank you Bjorn.

Sorry to revive an old thread. But since I am I was hoping someone could answer some questions or atleast point me in the right direction. Our Fire department has come across a m131A5 to use as a water tanker. But as stated before it has air/hyd brakes. We've heard of people taking the air brake components off of a 5-ton and replacing the air/hyd. My question is, Is this feasible? Thanks in advance
