Since you have 6 wheels, the TireMinder Smart TPMS for RVs # TPMS-APP-4 that you mentioned will work, however you won't have enough sensors for all six tires.
Instead, I recommend going with the:
-TireMinder i10 TPMS for RVs and Trailers w/ Signal Booster # TM29FR.
This TPMS includes 6 brass waterproof and dustproof sensors, that will allow you to monitor all 6 of your Winnebago's tires.
These sensors will alert you with changes to your tire pressure, tire temperature, sensor and monitor... view full answer...

For your 26 foot Class-A RV you can use either the ADCO # 290-52203 or the Camco # CAM45730 covers.
The ADCO SFS AquaShed cover works best for short-term storage in moderate climates. Heavy-duty, 3-layer fabric protects against rain, snow, and sun. Contoured fit matches shape of your RV. Secures with cinch ropes and straps with buckles.
The Camco is UV-resistant, water-resistant cover is made of polypropylene. A unique triple layer top panel provides maximum resistance to rain and snow. view full answer...
