What it is

RV Propane Cylinders Filled While You Wait

A camper relies on propane to run its refrigerator, stove, water heater, and furnace, and the supply always seems to run low the night before a trip. Bring the cylinders from the front of your travel trailer to our propane refill center, and we will fill them just as quickly and easily as a standard grill tank.

We read the collar date before filling anything. Camper cylinders spend years outdoors in the Texas sun and age out sooner than many owners expect, so we check it for you, and we can recertify the cylinder on site if the date has expired.

4-T Propane has a location at Buchanan Dam on Highway 29 and another at Marble Falls on RM 1431, on the routes many travelers take to Lake Buchanan, Lake LBJ and Lake Travis. Stop in on your way.

How it works

Three Steps Before You Hitch Up

  1. Remove the Cylinders

    Most trailer cylinders lift straight out of the rack on the tongue. Bring both in and you will not need a second trip for the other one.

  2. We Check and Fill Them

    We read the collar date, inspect the cylinder and fill it. If the date has expired, we can recertify it on site while you wait and fill it.

  3. Return the Cylinders

    Set them back in the rack, reconnect the pigtail and you are ready. Call the office before you set out if you want to confirm availability.

What we fill

Camper Cylinders, Checked Before Filling

Work cylinders and grill cylinders are filled the same way. See cylinder refill and exchange for details.

Trailer Cylinders

The removable cylinders from the tongue of a travel trailer or fifth wheel. Bring both in and we will fill them together, so it is one trip.

Date Checked First

Customer at the 4-T Propane front counter

Outdoor storage takes a toll on propane cylinders over time, and every tank eventually ages out. We read the collar date and tell you where your cylinder stands upfront before filling it, so you know your tank is safe and compliant before you head out.

Recertified on Site

If the date has expired, we can re-stamp the cylinder here, so you leave with it filled instead of being referred to another provider in town.

RV Propane Questions

Can You Fill the Tank Built Into My Motorhome?

The removable cylinders from a trailer are filled at our propane refill center. Call the office on (830) 220-9240 to ask about a motorhome tank.

What Do I Need to Bring?

The cylinders, and nothing else. Call the office on (830) 220-9240 first if you want to confirm before you visit.

Will You Fill a Cylinder That Looks Old?

We read the date stamped on the collar first. If it has expired, we can recertify the cylinder rather than turn you away. More detail is on our cylinder recertification page.

Which Location Is Closest to the Lake?

Buchanan Dam is on Highway 29 just east of the dam, and Marble Falls is on RM 1431. Both fill cylinders while you wait, so choose whichever is on your route.
