There is much to do, and much to learn as this will be our first Airstream, our first trailer! We are very green and we are looking forward to all the advice the is here to be had!
Now we need a tow vehicle!
According to Airstream's corporate website
, the following are base numbers for your coach:
- 31' Sovereign Twin -- Rear Bath -- International Package
- Dry Weight 5,005 pounds
- Dry Hitch Weight 485 pounds
- 31' Sovereign Double -- Rear Bath -- International Package
- Dry Weight 5,035 pounds
- Dry Hitch Weight 490 pounds
- 31' Sovereign Twin -- Center Bath -- International Package
- Dry Weight 4,920 pounds
- Dry Hitch Weight 695 pounds
- 31' Sovereign Double -- Center Bath -- International Package
- Dry Weight 4,915 pounds
- Dry Hitch Weight 730 pounds
Keep in mind while reviewing these figures that these base or dry weights do not include any options nor installed accessories. The weights also do not include fluids (water, LP gas, etc.) or any personal possessions packed in the coach. My suggestion would be to utilize the following approximations for the gross weight of your coach ready to travel:
- 31' Sovereign International -- Rear Bath
- 6,200 pounds Gross Trailer Weight
- 725 pounds Gross Trailer Tongue Weight
- 31' Sovereign International -- Center Bath
- 6,100 pounds Gross Trailer Weight
- 875 pounds Gross Trailer Tongue Weight
Many here on the Forums like to apply an 80% rule of thumb where you look for a tow vehicle rated to tow at least 20% more than the loaded weight of your coach. Your coach likely will weigh only a few hundred pounds more than my Overlander (I tend to over-pack, and my Overlander typically scales between 6,000 and 6,100 pounds with a hitch weight between 725 and 750 pounds) . . . when I shopped for my last tow vehicle, my minimum tow rating was 8,000 pounds (in reality, I went with a tow vehicle having a 10,000 pound trailer tow rating as it was a better buy than lesser vehicles that I considered).
Good luck with your tow vehicle investigations!
