I have a HiLO trailer and the main benefit with them is reduced drag when towing. Thats important for long distance trips, but not so important for a trip that is just a few hours away. Once you get past the towing benefit it generally goes downhill. They are HEAVY. my 22ft model is over 5000lb with the tanks dry. They are mechanically complex. They have a hydraulic powerpack that is needed (with a good battery) to raise the roof, in addition to the hydraulic ram which is under the floor and then a series of cables from the ram to various points around the trailer so they can lift the roof.
There is a seal between the upper and lower section that degrades quite quickly and is expensive to replace. The interior layout is highly compromised by the fact that the roof is lowered. Anything that sits on the floor, can only go to counter height. Think closet, refrigerator etc. Anything at ceiling height cannot extend down more than 12" because that is all that is left above the counters when it is lowered. Storage in them is highly inefficient. You also have to do a rigorous inspection before lowering the roof, since if you leave a broom in a corner you might find it sticking up through the rubber roof after you lower it. If you leave objects in the sink, they may smash the light fixtures under the overhead cabinets. On the outside, if the water filler cap is not replaced and the door closed, it will simply get sheared off when the roof is lowered.
I have one and we use it, but it is not the ideal trailer. I just bought a used Scamp trailer and it weighs about 2000lb, is full height, has a single axle (easy to move in the driveway) and the fuel consumption towing it is about the same as the Hilo since the scamp is much more aerodynamic. The scamp is by no means perfect and there are some weak points (they rivet the overhead cabinets to the fiberglass shell instead of bonding them to it without any penetrations). The rivets are point loads of the kind not recommended for composite and so they tend to work loose, cause cracks and need repair. But the trailer holds up much better than any kind of stick built trailer with their associated leak and rot issues. Overall the number of seams on a Scamp is 2, one at the belly line where the upper and lower meet and the second where the shell meets the floor. Fewer seams = fewer problems.
