In general, FR has decent stuff, but you do get what you pay for (don't expect a Maybach for a Kia price.) If I had the storage space, I'd buy a Solera (although I like the 24 R since you get a 26-28 foot motorhome in a 24' package, and if one doesn't get the entertainment center option, the cabover bunk is good enough for the quick naps without having to stick the rear slide out, although it might be a hindrance if one uses it for storage.) I'd probably doublecheck if the converter is multi-stage, (replace if not), and add an accumulator tank to the water pump. Not heavy duty stuff, but small modifications that make life easier.
Whatever you do, get the fiberglass nose and end caps. These will greatly prolong the life of your Solera by helping protect against water intrusion (and the cabover rot caused by that.)
