"Nuestra Casita" has had the frame extended 24" in the front. She has a diamond-plate box with a kind of foil backed "felt" insulation. The insulation is usually used on the underside of a car hood, or on the inside of car doors. It was fastened to all inside surfaces with 3M spray adhesive. No back or bottom on the box. There is a door on the side, to correspond with the exhaust location and the top is hinged to allow more ventilation when outside temps soar. The intent was to protect the extra quiet 3000 watt Yamaha from curious fingers and prying eyes. Out of sight, out of mind philosophy. The box has served it's purpose and also reduces noise. I suspect the reduction of noise would not be very effective with an open-frame generator. There is sufficient clearance between the generator and box to allow access to operate the key switch and choke and to plug in the electrical
cord. The box was custom built and fits on the TT frame rails. The top's hinge is 3 1/2" forward from the back edge and located in a trough which is open on the ends. This not only provides drainage, but stiffness and prevents contact with the Casita
belly-band. The top tilts backward enough to not require any support when open. The box is sturdy enough to support my 180#s, with a piece of plywood to spread the weight
. The plywood might not actually be necessary but why take a chance?
The only downside I've encountered... the box must be removed in order to change the oil or service the battery
for the generator.
We've used it for 3 years like this without any problems.
