.....I surely hate hearing about all the issues you experienced with your 315RST. Glad to hear that PT stepped up, but sounds like you had a lousy dealer.
I bought from a lousy dealer one time and I know the feeling. I found out the hard way it's always important of not only doing research on a trailer when looking to buy, but researching the dealer as well.
I was able to take all the time I wanted on our Crusader's PDI, about 1 1/2 to 2 hours. I only found a couple of cosmetic issues that they fixed on the spot. We also spent about 45 minutes in the trailer the week before when we went to just look. So we were able to look everything over pretty good before we purchased.
I have 50 amp service here at the house and can hook up to water as well. I have gone through all the systems on ours this past week and a half.....2 or 3 time each. So far so good.
I have also opened every window and all operate as they should. As well as every cabinet door and drawer.
All lights work. All waste tank indicators work.....how accurate are they
.....slide outs work properly.....the leveling systems works properly.....awning works great.....entrance door and all baggage doors open and shut properly and lock and unlock easily.
I'm not going to say I won't have a problem sometime down the road, but as of right now I haven't found anything wrong other than those during our PDI. I like to keep a close eye on things. It's kind of fun tinkering around with a new trailer anyway, but it also helps me to spot potential problems and maybe prevent them from happening.
It's good to know that you have gotten all the bugs worked out and you are enjoying your camper. Thanks for posting your experiences. I'm sure it will help others.
