Help Mr. Rastelli

Hi my name is Martha .. Mr. Rastelli daughter .. my dad is on a fixed income and he travels to Rodeos to take pictures of them. He has done this 40 something years. He continues to travel and that is how he earns his living other than social security. He is a hard working man and is to proud to ask for help. The new season is upon us and he is traveling in a truck that has no air and has over 300,000 miles on it and it worries me . Wish I could help him but I can’t .. please if you can help him out .. anything is appreciated ..
