Trying to keep my cool but sheesh am I frustrated. I will have my maiden voyage with my 87 Startcraft later this week. I headed on out to the air pump at a local gas station that provided LOTS of room for me to maneuver with the intentions of making sure my tires were inflated properly. I have Hi-Run 5.70-8 tires that says I have a max of 100 psi. Yikes!! That seems like an outrageous number. But in all the online researching I find that I should keep it at the max. Well, I can't get either tire inflated over 70. I even went to a different gas station thinking my pump hose was not working as it should. I don't have any mechanical mind to help me out, I am a solo camper. What on earth am I missing?? And how on earth do I get 30 lbs of air in? It would take forever! Do I need to buy a compressor???? oh boy.....I am thinking I can't go to gas stations... UPDATE cripes I feel dumb. okay so I learned that the typical gas station pumps are rated for 65-70 max so I can't inflate them there. (probably why I never saw any pups at one) Do RV dealers offer that service?
