Well 1st let me say that I was very surprised to find that you are in NZ and buying an American RV, funny! I would have thought that their would be manufacturers, that are local to the local, and maybe CrossRoads is one of those.
Problems: I had a few that I feel are simply manufacture short comings, and I will speak from the point of view of being a Canadian buying a USA built RV, as 90% of all RV are made in the USA.
1 Tires are cheap,I would expect to replace them within a year to prevent a blow-out on the highway.
2 Tires are under-rated for the weight of the RV, cost saving measure, buy the lowest grade, and rating for the particular model, expect to replace within a year and make sure you replace with tires that are rated for the weight of the unit (Loaded), I blew 2 tires out of 4 replaced with similiar one as I didnt know better and wore those out in about 2 years.
3 Axels are under-rated for the loaded RV weight, mine were barely speced for the un-loaded weight of the trailer. Mine bent and they axel frame shop would NOT attempt a repair as they explained that Lippert Axels, sidewall (on the actual axel tube were very thin and either kinked, or cracked when they had tried repairs. Dexter are much superior axels and can be repaired.
The complete alignment on our axels were so far out that the tires were scrubbing themselves to death on the inside 1/4 of the tread.
Dealer nor manufacturer would do anything which left me with replacing axels which I did and I went for Dexters and the largest rating I could go up without having to change the complete system that the axels mount on.
4 Electric Tongue Jack under-rated, hitch weight is 900 lbs, jack rated at 600, went thru 2 jacks, no warranty, til I finally sourced my own and made sure it is rated for 1100 lbs.
Expect to find things that simply make no sense as far a space utilization goes, ie: sink drains that are routed right in the middle of a cupboard, making the cupboard almost useless. I re-routed ours and installed 3 drawers under the kitchen sink to provide storage space.
Wardrobe closets in the bedroom DARK in the middle of the day, couldn't find anything with out a flashlight, I installed LED light strips on a magnetic reed switch, lights ON with door open, Off with door closed. Same as pantry/ closet by the kitchen.
No reading lamps for each bed, only 1 large lamp in the middle which when reading in bed at night (laying on your back) means you are looking right into a light, also what happen if 1 person want togo to sleep and the other wants to read????
Depending of year of built, I replaced ALL light bulbs in our unit with LED lamps, newer ones may already have this done.
Outside storage cupboards only have 1 light, pretty hard to find things I installed several low profile lamps through-out the cupboard to make finding those weiner roasting sticks easier.
All manufacturers cheap out on EVERYTHING, otherwise they would need to pass the costs on to the buyer and the buyer being cheap, would simply go to the lowest priced unit and a different manufacturer, this is the case for ALL units and manufacturers, even the $500,000 ones, in my opinion having discussions with other RVers.
In any case if you are willing to spend a few $$$ after purchase, within the 1st year all should be well and enjoyable.
