PPL Houston (and I assume New Braunfels) is a first class operation.
We purchased our first MH (and only, so far) from them 4 years ago. It's a great place to start. No sales pressure at all. You check in, get a listing of what's available and their pricing and then you're free to look at anything and everything on the property. If you have questions or need help - they're right there in the office and readily available.
After numerous trips to PPL we found the coach we liked and had the PPL rep act as the go-between with the owner. With an agreed price in hand, the PPL rep assisted us in setting up an independent inspection (on-site since we couldn't remove the coach for that purpose). Everything checked out and we were ready to go ... but then the rep called and said he didn't think the fridge was working correctly. They took the time to check it out over the next few days (at no cost to us) and determined that it needed to be replaced. Again, PPL worked with the owner, and a new unit was installed in short order.
Paperwork, a final walkthrough and off we went. A very plesant experience all around. We felt that PPL took care of us (newbies) and helped make sure our first experience was a good one.
