Mark’s RV Product Spotlight: Today I  show you how easy it is to install the most advanced RV vent cover ever designed, the MaxAir II vent cover on your RV. This new vent cover has twice as much vent area as the original Maxx Air vent cover, allowing even more fresh air into your RV, come rain or shine. These Maxx Air products help reduce heat build-up, let stale musty air and cooking odors escape and improve the inside air quality of your RV.

You can purchase Maxx Air II vent covers at Camping World.

What’s the difference between overhauling and rebuilding something? Well the best way I know to explain it would be using a car’s engine as an example. If you overhaul an engine you replace the parts that need to replaced and leave anything that still works properly. You might overhaul the top end and  never even look at the bottom end. When you rebuild an engine you go through the entire engine top to bottom. I have a feeling our trailer project started as an overhaul and is quickly turning into a rebuild project. But I’m having lots of fun with it.

Question #1  Hi Mark, What are the best products and methods for re-caulking your RV roof and how often should the maintenance be done and under what conditions i.e. weather and temperature.

Mark’s Answer:  Good question Jim. Let me begin by saying that it is important that you use sealants compatible with the material your RV roof and other products you are sealing are constructed out of. If you have the RV owners manual it will usually specify sealants you can use and what intervals you should perform routine roof maintenance on your RV. This is extremely important because in many cases the RV warranty can be voided if these inspection and maintenance aren’t performed. With that said let me tell you some of the products I personally use to seal and maintain roofs. I use Dicor 501 LSW Self-Leveling Sealant.  This sealant is used in the RV industry by original equipment manufacturers and for aftermarket use. It is compatible with EPDM and  TPO rubber products, galvanized metal, aluminum and fiberglass roofs. This dicor product is available at camping world. Another product I use for sealing and repairing RV roofs is Eternabond products. It’s compatible on all types of roofs as well and it goes on as easy as applying a piece of tape. Once applied it is sealed for good.

The second part of Jim’s question is, At what mileage or time interval should a travel trailer or 5th wheel have the wheel bearings greased?

Answer: That’s another good question.   Dexter axle recommends that along with bearing adjustment the wheel bearings should be inspected and lubricated every 12 months or 12,000 miles whichever comes first. Be sure and check your RV owner’s manual because I have seen intervals of 12 months or 5,000 miles as well. And keep watching upcoming episodes of Mark’s RV Garage because I will be inspecting and repacking the bearings on our project trailer too.

Mark took the RV on a 5 week coast to coast RV trips covering over 7,200 miles


What’s the biggest obstacle on a restoration like this? By far I would have to say water damage. Water damage on something like this is like cancer. When water gets in the wood it slowly starts to rot the wood and as it does it spreads further and further. The same is true with rust on a car. I have seen RV’s that look fine on the outside but under the metal or the roof there was literally thousands of dollars worth of water damage.

Mark’s RV Toolbox:

Something I never leave home without is a quality tire pressure gauge. Like everything else these days’ things are switching from analog to digital. Analog tire pressure gauges were the standard for many years, but advancements in digital technology have improved on that standard. In numerous tests comparing different type gauges digital gauges proved to be the most accurate tested.  Regardless of the type of gauge you choose there are high quality and low quality tire gauges available. Buying a cheap digital gauge would be the same as buying a cheap pencil type gauge. I never leave home without this digital tire pressure gauge by Tire Minder available at Camping World.  Here are a few things to keep in mind when it comes to tire pressure gauges:

1)   Spend a few more dollars and get a quality pressure gauge.

2)  If the gauge will be used for checking dual wheels on a motorhome the chuck end of the gauge should have a dual foot design to make the job much easier.

3)   Always select a gauge rated higher than the inflation pressure of the tires you are checking. Applying more pressure than the gauge is rated for can damage the gauge and affect the accuracy. If you over-pressure a gauge have it tested for accuracy. This gauge is rated up to 150 psi.

4)   Try not to drop or jar the gauge. Store the gauge in some type of protective covering or case and in an area where it won’t be hit or damaged. 

5)   Periodically have the gauge tested for accuracy. At a minimum compare it to another quality gauge to see if both read the same, or close to the same pressure.

6)   Most importantly, once you purchase a quality pressure gauge use it on a regular basis to check your RV and automobile tires.


Thanks for joining me today in my RV garage. Travel safe and have fun in your RV and remember when it comes to learning about RV’s we’ve got you covered. Be sure to take a minute and visit www.rvconsumer.com and we’ll see you right back here next on our next episode of marks RV garage.
