BUT... After their response to me damn near begging them to sell me some panels, with cash in hand, being completely ignored over and over, it doesnt even remotely surprise me
I think it's a good cautionary tale regarding companies who work in this niche market (or any niche market). Many are loath to pay for real engineering or R&D... they simply can't afford it like a larger company. Even if they had some good designs in the beginning, management and staff might have changed considerably in recent times. Most people simply don't appreciate the thousands of details that must be addressed, analyzed, tested, etc. So many ways to screw up. And some of these are not possible to fix without starting over. Like the box itself coming apart. You are basically buying a prototype, and you are the alpha tester...
For instance... a friend has a XP V2 (one of the few) on a Tundra. It is not perfect, but the issues were minor IMO, and easily fixable. And somewhat understandable considering it was a new design from a company that was already flirting with bankruptcy. Anyway he wants a new rig, and can afford a very nice one. I recommended a Nimbl, which without actually examining it myself (which I would do before
really recommending it), seems like it's one of the best sorted and least risky designs. He went to an expo and saw a Truckhouse and fell in love with it. That IMO is the quintessential example of a vehicle to avoid. Just say no! Not because I *know* it's deficient, but because the risk is extreme... not just on the camper, but the entire truck, which won't be warrantied by Toyota. That's assuming they ever get sold in the first place... the company could easily go bankrupt before they ever get started, and there goes your deposit.
As you are well aware, the chassis-cab frames are very torsionally flexible, and mounting a camper on an overland rig gets tricky. Unless someone really needs the capacity, it's much simpler to
get the fully boxed and torsionally stiff pickup chassis. The risk of overstressing your box goes to nil, you save the weight and height and cost of the subframe and pivots (or springs), and the box is no longer flopping around relative to the rest of the truck.
Regarding GXV saying that "customers will be taken care of if they stay mum"... if that's true, and I was a customer, I'd not be complying with that BS!!! Though I hate dealing with lawyers, it's time to get one.
Sounds like they are trying to hide it until warranties expire. They need to own up to the problem, hire some smart people to redesign it, and fix the currently defective hardware... whether the customer's rig has actually failed or not. That's how a reputable company operates. And if they actually did that I'd put them at the top of the list for "companies you can trust".
