I have had my Yakima box for about 15 yrs and love it.I'm not sure what model as the side decals have disappeared.Aprox dimensions are 90 in long and 15 in high at highest point. We use it for camping,first on a Subaru Forester and now on a 2016 TC LWB.My racks are adjustable and currently set at 36 in
I have barn doors so I don't know if liftgate models would be a problem.
I can mount it by my self because I have built a storage rack on my garage wall that is head height.It is very awkward to lift off the ground by one person .
It is best for lighter soft items,bedding,tarps,duffel bags etc.It is very slippery inside so use care with single items and hard partial loads.I believe there are tie down points inside but have never used them.
It opens from either side and the locks work well.Order extra keys.Never had anything get wet in probably 10,000 mi.
The only downside is the height .I am 5'8" and have to toss things up and then stand inside to arrange them with one hand.
Avoid parking garages and low limbs,I have had a few close calls.Fortunately just scratches
