Looking to buy a TM and have some questions

My wife and I are looking to buy a lightweight trailer and are seriously considering a Trailmanor but I have a
few reservations that I'm looking for help with.  

1.  Since the roof is sectional, I can't help but wonder if  anyone out there has had problems with leakage.
    I also wonder, if it's raining when you need to set up the TM, how does the interior stay dry during the
    setup process.

2.  When I look at the aluminum and polystyrene sandwich for the floor, walls and roof, I can't help but
     wonder if anyone has ever had any delamination problems?  The reason I ask is that they offer a lifetime
     warranty on the lift system but only 12 months on the rest.  

3.  Did anyone compare the TM to a Hi-Lo and if so what were the primary reasons you chose TM over
    Hi-Lo?

4.  I know there are pieces of insluated vinyl flap to create a seal between the top and  bottom sections
    but does that really keep bugs, dust, etc out?

5.  The Woodall's RV Buyer's Guide 2003 lists the TM's Roof/wall/floor framing as being Aluminum/wood &
    Aluminum/wood.  Does anyone know how much wood is used and what size (eg. 2x3) is used?  The
    TM brochure makes no mention of wood being used in the framing/structure.

I want to thank everyone in advance for any help they will provide.
