OK, I will give you my 2 cents on this. I have a 10 year old hull, so don't know how Oliver is currently dealing with their hull cutouts. But I can say with some certainty that square inside corners in a fiberglass layup is just poor detailing. Especially in a RV that is subject to all kinds of stresses and vibration. All corners at the very least should be drilled out with a hole saw to a diameter that is compatible with the appliance (or whatever) being installed. Then the straights can be cut out with whatever tool: angle grinder, router, jig saw etc. seems best. The hull on my rear Oliver lense had square cutouts, and I have similar spider cracks at two of the corners. I checked my HWH yesterday and the hull was also square cut under the rounded metal flange. Last year my friend had to pull his HWH and his hull was also square cut (pretty badly as we recall). No spider cracks yet on ours but.... Look up in your attic at the back side of the Oliver light. If it was square cut, then that is a good indicator that your HWH is the same. You can also look from the inside at the HWH and see what the corners are like. If it is square cut, then the only repair I know that will last is to create a radius at the corner to spread out the stresses that concentrate there. This is what I did on my rear lense in the pic. For you, that will be a real PITA as the metal trim ring has to be removed and who knows what else. Mine is set with butyl tape and pop rivets. As I mentioned, your crack is probably just in the gelcoat and not structural. But it shouldn't be there in a trailer of this caliber. Any repair that doesn't address the root cause, will be wasted effort and money IMHO. Wandering Sagebrush's idea to drill a hole at the end of the crack could work. I have used "stop drilling" to stop cracks in fiberglass layups from migrating, but then you have a hole that needs to be gel-coated and polished out. Not sure if it would work for just a gelcoat fracture. Maybe a good solution? It could be! In the end, a good fiberglass technician will know what to do. But I think it will not be a quick and easy fix. Please post up what you find out. Good luck. Dave

Agreed. Although there was a moment when I first posted when I thought I was in the wrong thread. Carry on. Dave

Seems like we have some serious thread drift going on here.... Dave

Inside corners are a typical area where gelcoat, which is relatively brittle, can fracture. Which is why it is never good practice to have square inside corners that concentrate flexing at a single point. Surprised you had a fracture with a nice radiused corner (Or is it? Is there a square cutout in fiberglass under the round WH flange?) Pretty sure the crack is just in the gelcoat and does not mean the fiberglass underneath is also cracked. So mostly just a cosmetic defect. Not sure how to "repair" a crack like that, and if a repair wouldn't suffer the same fate over time. Hopefully someone may know and chime in. Sorry to hear about your other woes. Our 10 year old trailer had some issues at the start, some also potentially dangerous. But since getting all that sorted, all has been great. Just had to replace my plastic toilet flange that was broken. Just the usual maintenance one would expect over time. Good luck. Dave

For the Commercial flaps, I read 85 inch-pounds. Even small bolts need special care in certain situations! Not that this is one of them however. I did just notice that after my recent trip before my last post, that one of my bolts had fallen out somewhere. So I emailed Rockstar about the situation of their torque spec and the rubber flaps not being able to support that kind of compression. I asked if using blue loc-tite would be a better solution. All they said was yes it would be OK. So I redid all the bolts with 5/16x1-1/2" SS fender washers and Blue loctite. With the larger washer, I was able to achieve 85 in-pounds with minimal distortion, but it's really probably not necessary with loc-tite. I just did it to see what would happen. Even with loc-tite and less torque, I think a washer is a good idea however. Dave

Took me a while to get to this.... I also have the Rockstar Commercial Flaps on my rig and really like it. My old flaps clamped on to my ball mount shank and were just OK. It made removing and placing the ball mount a very cumbersome and heavy affair. These are way more convenient to put on and take off since they are separate from the ball mount and do a much better job protecting the trailer from flying debris. Perhaps because they sit further forward under the bumper. My rig is gas but the cutout is similar I'm sure. Perfect fit. I added stainless steel fender washers to the bolts that attach the crossbar to the rubber flaps to spread out the load. The torque spec in the install guide was pulling the heads too deep into the rubber for my taste. Even with the washers, I didn't get as tight as was specified. But no issues with many miles on them. You'll love them! Cheers, Dave

OK, better pic.....

I just completed a Victron update to all the solar components in our trailer, including the Victron 50amp DC-DC charger. It has been great. I was originally thinking of doing the work myself but soon realized I was too far out of my comfort zone regarding the complexities of the install. This job I delegated! Expensive, yes. But The job as it was done went way beyond my expectations. I was very lucky to find an outfit locally that really knew what they were doing and take great pride in their work. The cost of the DC-DC charger was part of a much larger project so hard to break it out. There will be two sides to your install, the TV and your trailer. I found a way to fish 4awg cables from the streetside rear dining seat (where the battery box is) forward, under the bathroom sink, and then out the front of the trailer next to the 7-pin plug cable. The charger is mounted on top of the battery box. My truck luckily has a battery distribution fuse block with multiple fuses up for grabs including a 60 amp fuse to which the truck-side wiring was attached. The truck wiring terminated with an Anderson plug that was bolted to the underside of my bumper with a custom bracket directly under the 7 pin plug (which is next to my license plate). This location I highly recommend as it makes attaching your fairly large 7 pin and DC-DC charging cables nicely aligned and easier to manage. I'm getting similar charging profiles as JD iirc. For me, I don't like traveling with propane on, so I switch to DC mode on my fridge when under way. Always have full batteries on arrival! These new lithium batteries charge up fast if they can get the power and this little charger really delivers! Of course, it only works when your running your TV. So, as JD mentioned, this will be of no benefit if boondocking and stationary. That's where your remote solar panels come in to play if you have them. I suppose worst case, you could use your TV as a giant generator to charge your batteries but many campgrounds, especially in the National Park system, or in CG's that don't allow portable generators, this would not be allowed. Super glad I got the charger, no regrets! 👍👍 Dave

I don't have the Truma, but on mine, the condensate line at the AC was not hooked up at the factory. I'd pull off your interior cover and see if yours has come loose, or was overlooked at the factory. Easy fix if that is all it is. Good luck. Dave

As far as the more traditional RV hoses that won't collapse in a siphon scenario, the very best that I have found are the ones sold by The Water Filter Store. The fittings are excellent and the hose is also very high quality material. They will also custom make them to length as you require. https://www.rvwaterfilterstore.com/products/custom-built-hoses Dave

OK just checked my PM's and looks like my charger has found a home in csevel's Ollie! 👍 Onward. Dave

Right you are! I was thinking of the service rating for the trailer. It is a 45 amp charger. Hope someone could use this. I was hoping to keep it "in the family"! Cheers, Dave

I will mail it out to anyone who could use it FREE of charge. PM me with your address if you are interested! Dave

Yes it does! You can see it in the bottom left of the pic. It's a small switch. Dave

Greetings all, I bought this 30 amp charger from Etrailer a while back when I was planning to convert to Lithium batteries. My plans changed in the end and I ended up using all Victron components. I'm sure it's too late to return it now. So, if any one out there could use this brand new and never used/installed PD 30 amp converter/charger, I will mail it to you free of charge. It does have the Lithium switch. Model Number PD4045CSV Serial Number A24225FO325851 Cheers, Dave
