We chose the amerigo FG-16 (1973) partly because it was "there" --
I prefer the trillium jalousie windows
We like the amerigo double-fiberglass ceiling (yes, standard) and are not tall, so the 6-foot interior height is fine for us. That's all you get, six feet of height.
We were comfortable doing the all-wood interior, or should I say completely RE-doing it. In 43 years it had mostly delaminated into shreds, with only the PO's (POS) paint
job holding parts of it together.
We redid the beds from two gauchos (50" and 40" wide back and front) to two slightly narrower than twin beds plus a permanet 2-person seating area with a small folding table that lives in the front closet/porta-potty niche we call the "putin." We widened that doorway considerably, making access MUCH better. We also call the porta-potty itself the putin, partly because we put things in it (uh huh)...
We simply each need our own bed. This way we have a front bed and a rear bed, with room for some judicious curtaining for different sleep schedules, and putin privacy.
We feel there is a LOT of interior space; good to have with two little old pug girls scrambling around underfoot; good for me as I am thin-challenged...good for Paul as he gets a little claustrophobic when having to push past in a narrow area. We also went ahead and gave ourselves a few inches MORE room in the interior as we rebuilt, to the point where people have suggested it's wider than the 7' that it is. They said it looks more like 8' wide inside, which it is not.
ANYway, thing is, your mileage may vary. What you want most is what's most important.
We're no longer sorry we bought the amerigo now that it's finished and we're camping in it; during the 9 months of rebuilding we had moments when we knew the only way out was forward.
Not sure why the amerigo roof would leak worse than any other roof; once you cut a vent hole or a fan hole or add awning
railing or "whatever," that area is prone to leak if not sealed well--if sealed well, then same-o, same-o it seems like.
You have an interesting choice here; hope it goes very well indeed for you!
