Thanks Paul. It was because of you that I started looking at the right places. There is always a firstHaqi,
Am glad you got it figured out. While I have extremely limited knowledge on the subject, I believe your the first to experience a double relay failure.
I had emailed an friend earlier asking if he would chime in on the subject, he had an excellent write-up on removing the relays and installing a switchable circuit breaker. When I saw that you had fixed it, had to send a never mind message.
I had replaced my relays with a Victron 65A Smart Battery Protect, and wired it so that the Control Panel wall switch still controls the control panel (via the Smart Battery Protect) and didn't lose my step well lighting.

Excellent work friend. Your wife did an amazing job on the spare tire covers. Very creative indeed. I also love the refrigerator panels. Definitely a good looking mod that will outlast the factory panels. Plus, I think it matches the interior well. When I was looking at the BS trailers, I figured a set of 40# tanks would fit. Looked like the clamps had enough adjustment in them. Was that the case, or did you have to modify any of the hardware? I'm 95% ordering an Xplore trailer, but I keep going back and looking at an HQ19.Hello HQer's. Let me apologize in advance if this gets long, but I have quite a bit of info to share with you. I'll attempt to upload some pics too.
Issues,
-Trim and interior panels delaminating, cracking, warping, and falling off. The delaminating has been relatively easy to repair. I found that 3M Hi-Strength 90 works well on trim and panels that have delaminated but not cracked. As far as the warping and cracking, the refrigerator panels warped to the point of cracking and breaking the upper trim on the freezer door. I alerted Black Series and they sent me new refrigerator panels, however, knowing they would warp as well (and they have), I wrapped two aluminum panels cut to fit with carbon fiber wrap, and slid them into the doors. Lots of compliments, and no more warping. As far as some of the panels that are cracking, I've not yet addressed. Any ideas guys?
Question(s),
I have no issues with the polyblock hitch, but was wondering... I've seen other hitches mounted to bottom of tongue, does anyone know if the polyblock can be moved to the underside of the tongue? This will help the trailer tow closer to level.
Has anyone taken their rigs to a public scale to be weighed, I'm curious how accurate the Black Series specs are? I know of a couple of scales near me, I may hook up and find out.

I have been looking at the HQ19. Sorry about all the fixes. Every RV that I have ever purchased has had wires labeled. Having non matching tires is pretty odd. Can you continue to share your experience with the trailer when you use it. I am also interested in what tow vehicle you are using. Wondering if the experience in the tow vehicle cab is unpleasant, etc. Some trailers tow a lot better than others. Thanks and best wishes.
Not sure if you're on Facebook but I highly recommend that your join the "Black Series Camper US" group if you have not already as it has a ton of information and the members their are very helpful (Black Series in my opinion, not so much).
The delamination of the wood veneer is a known problem for these rigs and I have seen a few dealers, shops, and members end up wrapping those areas in other materials (i.e., leather).
Now about that polyblock hitch. I have not seen anyone mount it to the underside of the tongue and I don't think its worth the effort. You're better off getting a new hitch on the two vehicle that either has a rise or drop. You seem like someone not afraid to perform some mods so I highly recommend you get rid of the Polyblock (after a few hookups you'll think me) and instead reach out to Caravan Specialists (https://caravanspecialties.com/) and get yourself a McHitch which you'll see that folks sometimes mount them underneath the tongue.
I did not see you mention it but you should also consider having the wheel bearings on your HQ19 checked to make sure they were properly greased, especially before doing any longer road trips.
Thanks. Much appreciated. Good to know that a well equipped 1/2 ton can do the job. I have a F150 with the 3.5 and a tow package—roughly same capacity as your truck. Seems like it should be fine.My tow vehicle is a 2020 GMC AT4 6.2L with the trailer tow package. It's rated for 9,200 lbs, the "Max Trailering Package" would get me up to I believe 12,000 lbs. Anyhow, it has some nice towing features like the cameras, and sway control. It tows very well, however, I did notice the heavy tongue weight as mentioned above. I took steps to mitigate the issue since, and will monitor as we travel. The tandem wheels are the way to go if your rig can handle the increased weight, likes to go straight and a bit more stable over rough terrain. Additionally, when I had it delivered, the shipper drove a GMC 3500 HD dually, he said it towed excellent even up to about 75. Don't know about higher than that, and I wouldn't tow that fast anyways.
Thanks.
I haven't had issues with the polyblock, but I have seen the McHitch. Looks like a good setup. I think I'll take a closer look at it now.
I do plan to check the wheel bearings, are the extra ones they provide the same as what's installed?
Something I forgot to mention in my long post, some have stated to zip-tie the shackles for the suspension chains so they don't vibrate off. I looked at mine after reading that and observed that they had already been zip-tied by the factory. Someone there must be paying attention. If they had not been, I probably would use red Loc-Tite on them. I read earlier that someone suggested that. I may still do it, probably a more permanent fix than zip-ties that will eventually get brittle.
Thank you all.
Hi All, I just bought a new 2021 HQ-12, towing with a Tundra Crewmax, 4x4, 5.7L with Fox 2.5 adjustable coil-overs, lifted maybe 3 inches. Extremely pleased so far after our first weekend out. I noticed that when the tanks are 100% full (freshwater and drinking water) the tow was perfect, I didn't really push it on the highway maybe up to 70 max, but kept it around 60-65. Smooth as could be, extremely stable, zero sway. After the weekend, I decided that I would empty the tanks when I got back to my RV storage. The grey water tank was at about 50%, black water tank 45% full upon the end of the weekend. Immediately once on the freeway, I noticed it started swaying at about 62-64 MPH and got worse the longer I stayed at that speed. It was actually a little concerning. Any suggestions? I was thinking about adding Airlifts to the Tundra, and also I want to upgrade the tires on the trailer to a 10ply or something similar to what I run on my truck. Aside from this, we love it! Seems to be built solid, and I agree with some of the other posts, the bed needs to be topped with memory foam or something similar. Oh, and the TV speakers were the worst I have seen on a TV, not really a black series issue but cheap RCA? Anyone else experience this? One more thing, I think I may add the "poop tube sewer hose mod", I like the idea of keeping that mounted under the rig and out of the way. Look forward to more posts in the future.
Has anyone else found any other sway control solutions for an HQ12 other than having full tanks? My HOA doesn’t allow me to park it at my home so I’ll need to drive the empty rig not infrequently back and forth to the rv storage lot.
Thanks.
