Re: New Roadtrek RS E-Trek
The right box could be vented but it could not be enlarged in width because of the exhaust pipe and frame locking it in. I've carried disposable 1 lb. cylinders and on a typical 6 week trip I would use maybe two at the most. If the left box is enlarged enough to hold the 4.25 lb. cylinder I suspect there would be room to put a 1 lb. cylinder in as well. The other location to carry 1 lb. cylinders would be the outside skirt slideout storage box where the the electrical cord would be carried. There is room there as well as it is bigger than my Great West Van box that I have used for the cylinders.
