I am planning on adding some PUGs too ( or similar) in the future.

I think because of the HEIGHT of the bunk tops, I am just going to have my wife help me.
I also think that the HIGH or TOP edge of the blanket I will add a piece of long rope, this way she and I can just WALK the covers back to the roof edge, then find a way to secure them.  might need to bring a 4 foot step ladder or 3 step folding stool though as well.

When you order them, ask them to put velcro on the PUGs for you so you can velcro them to the trailer.

they are more important on a HTT, than a pup. this because the canvas ends on a HTT are more likely to have condensation than a pup, since pups breathe easier than the HTT.

IMHO, PUGs or solar blankets are a must for an HTT.

While I did have pugs on my previous two pups, I get absolutely no condensation on the tenting inside my HTT.
Maybe it's the Sunbrella used by Passport. It is never damp inside after three years of camping with it, over 140 days from March to November.
The only reason I'd get pugs for my HTT would be to keep the tree sap off the bunk ends.

I posted this a while back about how I attached them to our HTT (now sold), if it helps any.

I did order the PUGs with the velcro pre-attached.  They did seem to make a pretty big difference in heat retention, especially when combined with the Reflectix window inserts.
