Im getting ready to buy an enclosed race car hauler. I have raced dirt tracks for years but have always pulled an open trailer. Now im racing drag cars and think its about time to buy a enclosed trailer. I sure hope some of you guys who already own one can answer a few questions for me.

1) Is it better to have aluminum or vinyl interior walls and ceilings? ( not into painted plywood)

2) Theres a huge differance in price between say a Pro-Line trailer and a Pace trailer, is it worth it to pay the extra? I dont think i will be towing over 5-6 thousand miles a year. Are Haulmark Trailers as good as a Pace trailer? If there are better bang for the buck trailers out there please let me know ( Northern States suppliers )

3) Are the channel framed trailers as good as the boxed frame trailers? I have always pulled a channel framed open trailer without any problems.

Plain and simple, i guess im asking what brand of trailer you guys would recommend. Yes price is a big factor.
I talked to a guy at Pro-Line the other day and he informed me that a 2007 enclosed 24ft trailer with vinyl walls and ceiling, any colour i wanted, 10,000 lb. rating axles was in the $5,000.00 price range, I thought it was a good price, but are the trailers junk or are they worth the money?

Any help is always appreciated.
Thanks
