As noted above, do not ignore the need for a brake system while flat towing. Not only is it the law, but if you cause an accident and don't have one installed, get ready for a lawsuit. I used a hitch adapter brake system, has a cable you run through the firewall and attach to the jeep brake pedal.
The recommendation for protein for adult male vegans is around 63 grams per day; for adult female vegans it is around 52 grams per day. It is very easy for a vegan diet to meet the recommendations for protein. Nearly all vegetables, beans, grains, nuts, and seeds contain some, and often much, protein. Fruits, sugars, fats, and alcohol do not provide much protein, so a diet based only on these foods would have a good chance of being too low in protein.
Tofu: Good News for Vegans. Tofu is another excellent source of calcium. A serving contains over 500 mg of calcium, so even vegans, who are often left out in the cold when it comes to getting the nutrients they need, can still find ways to get calcium in their diets.
