Because we are about to order a Hallmark, new.... I hope you would share a few more specific details?
(1) The Torklift AnchorGuard turnbuckles were assembled incorrectly by Hallmark which caused them to come loose. One loosened so much it fell off in the first 500 miles from the factory. Hallmark also purposely reversed the front and rear turnbuckles because they “worked better that way.” I contacted Torklift and they diagnosed the problem, sent me two replacements that had been damaged, provided detailed directions on proper assembly, and checked back to make sure everything worked.
(2) Hallmark installed Happijac front tiedowns which included bumpers to align the front of the camper with the truck bed. Unfortunately they neglected to allow enough spacing for the camper’s battery compartment flange which rubbed and damaged the front of my truck bed.
(1) Several minor adds agreed on were forgotten. A couple were taken care of during installation whereas the rest were sort of covered after reminders. Also, they added the radio which we specifically asked to be deleted.
(2) Some work was sloppy with screws missing their mark. Shelves in one cabinet were installed without any restraint so fell off after a few bumps. The flush solar panels are coming undone and there are exposed wires that should have been covered.
(3) The limit protection on the automated lift top did not work. The tank heaters and gray water drain were not described during orientation which caused problems when I misunderstood how they worked.
(1) Most of the plastic parts (water valve, screen door latch, door holder, outside shower, dinette table mount, Venetian blind caps) have failed during 4 years. They are inexpensive (if annoying) to replace but could have been much better quality. I have also replaced a couple of the roof latches which are thin metal and easily damaged by tree limbs.
(2) Drawers are friction and are retained by notches which do not hold on bumpy roads. That is simple but ineffective construction. RVs of this price should have slides and secure marine latches.
(3) Controls and indicators are basic and mostly unlabeled. Rocker switches are far too easy to accidentally hit. The tank levels are highly inaccurate. The thermostat is a basic residential type that is annoying to use in an RV.
(4) The Euro-style Dometic sink and range are fine although the little caps are prone to fall off and are difficult to find replacements. Keep some glue handy.
(5) Thin, single-pane glass windows are major heat leaks. Hallmark provides some snap-on fabric covers but those are awkward to put on and remove. They did not want to install Euro-style insulated windows with integrated blinds.
Hallmark has a solid product and with a little more attention to detail could be outstanding. Hope that helps.
