Expert Reply:
There are going to be two options for best caulk or sealant for your RV and it is going to depend on where your are using it. If you are on your roof you will want a self leveling sealant like the Alpha Systems 1021 Self-Leveling Sealant for RVs - White - 10.3 oz - Qty 1 item # AL98KV. This sealant can be used on skylights, vents, and other horizontal surfaces of your RV roof. The strong, weather-resistant formula works with rubber, metal, and fiberglass. It is a rubber based formula which will give it flexibility while you are traveling.
It is also available in Black item # AL48KV, Almond item # AL88KV, and Beige item # AL78KV
If you are not working on your roof you will want the Alpha Systems 1010 Non-Sag Sealant for RVs - White - 10.3 oz - Qty 1 item # AL28KV. This will allow you to seal the sidewalls, end rails, and other vertical surfaces on the exterior of your RV. It works on wood, metal, and glass.
It is also available in Black item # AL53KV and Gray item # AL33KV.
If you need a caulking gun I recommend the Performance Tool Heavy-Duty Caulk Gun - 10 oz item # PTW54295.
