I can not speak of quality but I can of Maintenance.
Maintenance for a regularly used motor home, is not a lot different than a truck/trailer combination (Technically a semi truck, did you know that).
With your current trailer you have basically 3 systems
Truck (The tow vehicle)
Chassis (Basically wheels, bearings and brakes, not much else to go wrong there)
and HOUSE (The rest of the trailer.
With the Class A you have
Truck
House
Of course if you let it sit for extended periods of time (Months on end) you MAY have "Storage" issues.. Motor vehicles like to... Well.. Motor (Travel) Trailers do not mind being parked so much. (Basically only tires go bad in long term parking provided house is maintained).
That said.. Many motor homes sit six or more months a year with no tribble.
Recommendations: Practice driving after hours at a shopping mall at a time when the only thing to hit is the brakes.
SCALE the beast, fully loaded for travel, get the weight on all 4 corners. (Each wheel). and inflate tires per tire maker's inflation chart (Many like to add 5 PSI, myself included).
If you need help doing this, www.rvsafety.com (If I got it right) is the web page that you go to to schedule an appointment with their weighmasters who come out with PORTABLE scales.. Look about for a good weigh spot and meet you.
They do a lot of the "Leg work" too (Have the make, model and size of your tires handy when you call, IE: Mitchlin xrv 22.5xwhatever.)
