Which propane tank are these? Need to replace.

If the refiller cracked open the fixed liquid level gauge ("bleeder") and didn't close it tighty, that could easily account for the smell and "leak". Make sure the screw valves on the side of the service valves are closed tight with a screw driver. "Righty tighty"...

What would cause a tank to vent when it is laying on it's side?

Those tanks look to be in good shop. Get them to a Re-Cert stop, cheaper than new tanks, good for another decade...

I did that in my trailer days a couple times... No need to replace a perfectly good tank.

I have had a tank valve leak if it was not closed 100 percent or opened 100 percent. If you only open the valve a couple of turns, it 'could' leak..

I'm not sure how a propane hose gets "clogged"?? I'm still on my original 15 year old hoses and regulator on my rig and they are just fine.

I've replaced several tanks over the years, but mine are only the little #20 or the standard BBQ tanks.. I do the exchange station swap when on of my tanks is getting too old.. I just swap for a new partially filled tank for $20 and I'm good for another 12 years and I just refill as needed.

Anyway, you can get those existing tanks recertified or spend a lot of $$ to buy new ones. Your choice.

Personally, I'd just switch to a pair of #20 ones and call it good.. Unless you need the capacity of those larger tanks for long trips at a time, there is no reason for the extra capacity, unless you just never check them between trips..

Anyway, good luck! We all do what works best for us, so this is just what I would do with the way I camp.

DOT Certification Requirement for portable propane cylinders WAS 12 yrs after date of mfg as stamped on collar

That requirement was modified as of Jan 23, 2017
12 yr certification was changed to 10 yrs

5 yr 'Visual Inspection' still 5 yr
7 yr 'Proof Pressure Testing' increased to 10 yr
12 yr 'Volumetric Expansion Testing' lowered to 10 yrs

Info is slow to update....SOME Bulk Vendors have new regs.
Some mom/pop outfits still using 12yr

Those 30# 'Cylinders' are more then likely NOT leaking....rare without damage to leak.

After filling they can smell of propane due to propane spraying on them from 'bleeder valve' being open and/or when hose/nozzle assembly is disconnected

Propane Cylinders 10 yrs old (older) do NOT need to be replaced unless DAMAGED

Your 30# propane cylinders just need to be re-certified
Visual inspect is good for another 5 yrs. Then another 5 and another 5 etc.

Take them to a Propane Vendor (Bulk---Amerigas, Ferrel Gas etc) and have them re-certified for $10----$40 (pricing depends on Vendor)
Heck of a lot cheaper then replacement of TWO 30# propane cylinders which not only would be cost of replacements but then they would have to be 'PURGED' and then filled.

Just get them re-certified

And check that the 'bleeder valve' on neck of Service valve is closed
(Just SNUG do NOT crank/go gorilla on it. It is a needle valve and doesn't take a lot to shut off)
'Bleeder valve' is indication of liquid level when filling.....fixed tube at 80% level

That is why I changed to the 20 lb. ones. When they close to date I swap them out at homedepot or where ever and never worry about having to buy new ones. I keep a extra full one locked in the bed of the truck for when one runs out and then get the empty filled or exchange it.

x2 vertical tanks like those should always be stored and transported vertical

I too doubt the tanks themselves are leaking. Take them to your local propane supply company (not a tank replacement place) and have them recertified.

spray bottle with dawn and water should find your leak

Yup spray the fitting, hose, and fittings under the trailer where it goes to the stove, furnace and HW heater. Look for bubbles.

The tanks appear to be #30 tanks

If the tanks are leaking soapy water will show the spot. I would do this before you replace. You can have them re-certified at a commercial propane dealer and leak checked for that matter. I would do this before just buying new.

BTW if the regulator is also 10 years old I would replace. If you have a choice I recommend Cavagna brand. amazon

And yes it looks like standard 30 pound cylinder.
