HELLO FOLKS. First time travel trailer purchaser here. I've been looking for several months and finally fate brought me this 1973 Holiday Vacationer 20ft. Looking pretty good for $900. I was hoping for any input from anyone familiar with HR trailers and if anyone has copies of any manuals from '73.... I am also wondering if I've got an inadequate tow vehicle now, this thing is built like a tank! I'm unsure of overall weight, but I'm guessing over 3,000#... Well, what do you think? Good purchase or no?? Wish me luck! :)
