RE: Holding Tank Treatments and Your Advice on Lubricants

The knowledgeable RV people had me spending money on RV tank treatments, then I figured out they were not so knowledgeable. Tank smell inside the RV? The system is leaking and a plumbing smoke test will find the leak. NO chemicals for me. If you have money in your wallet Camping World and WalMart have a product to remove it. I added Zerk fittings to the holding tank valves and give them a bit of grease every now and then. I really do not care that petroleum may or may not be good for the seals, they are not going to last forever and I do not want to deal with stuck valves. I had my last RV 10 years full timing and the grease did not destroy the seals.

RE: Tire engineering question.

So I go and get rig weighted and inflate rear tires to 10% over psi suggested in load and inflation tables. I DID NOT HAVE A TIRE FAILURE. I keep getting told to run tires at much higher pressure in case I get a blow out, makes no sense. Your tire failure may have been totally unrelated to air pressure. Still, I am curious: how did "10% over psi suggested in load and inflation tables" compare to sidewall max pressure? In my mini Toyota sidewall max psi is 65, load and inflation table load range D tire calls for 39 psi, I run 43 and use TPMS. Sorry, but in my mind a blow-out is a tire failure. I am always curious about how folks use load/inflation tables. I see a lot of reference to them. I go with the advice of my neighbor, who is maintenance director for a large commercial truck leasing company. He manages the tire program for a fleet of several hundred tractor/trailer units. His advice to me for my motorhomes has always been to inflate to sidewall max pressure and go. Under-inflation equals excessive sidewall flex, equals excessive heat, equals blow-outs. Everyone has an opinion on psi, even some high end fleet people. Now there is a company that has been in business over 100 years, has billions of miles of tire experience. Bus loads of engineers, truck loads of computers. Access to data and studies from gov, university's around the world. Michelin made a film on how to weight and determine how much psi should be run in tires. Michelin is also financially responsible if the info is wrong. So do I trust Tommy tire the guru or Michelin? I'm going with Michelin! The argument always is you will get much better mpg with higher pressure. Show me one credible study that shows this. I cannot find one, only that the difference is negligible.

RE: Tire engineering question.

Most chinese tires specify that they should be inflated to max pressure at all loads. If you unmounted one and felt how thin the sidewalls are you would understand why. I have never seen that on a Chinese tire?

RE: Tire engineering question.

I did not think of trailer tires when I posted! Interestingly I never considered psi for trailer tires as I never pull a trailer. So I took a quick peek and I'll be, load and inflation tables for STT! https://tirepressure.com/special-trailer-tire-load-and-inflation-tablehttps://tirepressure.com/special-trailer-tire-load-and-inflation-table

Tire engineering question.

So I go and get rig weighted and inflate rear tires to 10% over psi suggested in load and inflation tables. Driving along and whats that BOOM noise? Got a blow out on the rear. In a miles long construction zone with no exits or place to pull over. Now one tire on one side is way overloaded, on my RV would be about 30% overload. Question would be how far can I drive on the remaining tire before destroying it or needing to replace?

RE: Fresh water tank leak

Discovered a small crack in the tank. Anyone ever repair something like this with Flextape? Anything advertised on TV is usually not worth what you pay for it! Some tapes might work, some glues may hold up. Welding is simple and will not fail.

RE: Maintaining air pressure in your tires

I'll second the China solar TPMS. I use a set of 4 on the duals. Not NASA accurate and have some quirks but never fail to report a loss of pressure. They tend to last about 2 years and I buy 2 at a time as there are no replacement sensors available. I use to spend too much time trying to balance psi in tires, the TPMS showed me pressures are all over the place. The outer tire in direct sun can have higher pressure than the inner dual and sun side tires will be higher psi that shade side. Picked up a nail during the day and was losing pressure, inside dual of course! Would not have known without the TPMS and would have ruined 2 tires. Unless of course you think that driving all day on one tire does not hurt it?

RE: Yamaha 2000iS and softstart with AC?

After getting internet advice and wasting some money trying to run a roof air on a Honda 2000, I use a 8000 btu window AC for my little Toyota, I added a hard start to the AC and the mighty little Honda runs the AC under all conditions, Rocky mountains to Death Valley. Mini split AC would be my first choice but I do not have room for evaporator. Home Depot and others rent Honda 2200's, rent one on the hottest day you can, AC draws more power as temperature increases. And at high elevation if possible, gen output decreases at elevation.

RE: Wheel simulators, tire valve extensions and other questions

Simulators and extensions, don't like them. Lug nuts if coming loose will leave a rust stain, can't see it with simulators. Almost lost a $400 tire due to failed extension. Holding tank leaks, do not bother with different glues and adhesives. Unless you want to put a screen door in the bottom of a boat the Flex stuff is not good for much. Your fresh water tank is a whitish, clear color? Google how to weld polyethylene or RV fresh water tank, sounds difficult but very easy to do and works well. Do not need to buy a welding kit for one simple repair.

RE: Screws backing out

Further to the good advice above, I would ask why they are coming out, and why they are stripped. That could be a red flag. Pull a few right out and look at the threads. They should be clean and metal color. But if they are blackened or rusty, you have a water leak problem. The screws are coming out because the wood is wet and rotting and no longer holds the screw. I'll second this, something is wrong. I have a 94 Toyota with over 100,000 and the screws do not just come out!

RE: how long to lower temps When living quarters at 100

Not an AC guy Delta T of 20 is considered normal. First thing to do is make sure filter and more importantly evaporator and condenser coils are clean. I have seen good AC units replaced because of cruddy coils! What I do is open a roof vent to give the hot air someplace to go, I leave one open for 20 to 30 minutes and sometimes when I forget a lot longer!

RE: Cleaning up our old RV

A decent caulk gun makes a big difference. Most go to Home Depot or such and spend $4 on a ratcheting caulk gun. Unless you are incredibly gifted it is **** near impossible to do a decent job as they cannot provide a steady flow. A $20 smooth rod caulk gun makes a BIG difference. Google caulking tips before you try again.

RE: Fuel tank electrolosis rust removal

F When I got the tank off it was so rusty inside (outside looked good) That I was unsure if it was salvageable. I thought it was ok, but not sure. Asked at the local NAPA who redid tanks and they recommended a AC/radiator place in Cape Coral. Took it there and they assured me the tank was worth saving, chemically cleaned and lined inside of tank for $245. They had the tank for 10 days. I am 73 with a bad back, hip and shoulder, the idea of doing the tank myself quickly lost its luster. I did remove and replace the tank myself.

RE: Tire Recommendations

Interesting, High quality brand name tires?? Are they better tires or is far more money spent advertising them? Is a brand name tire in Europe or Asia unknown in the US? And brand name in the US unknown in the rest of the world. Expiring minds need to know. Seems as if one tire was so superior that no money would be spent on advertising, word of mouth would be all that was needed.

RE: Marathon driving

A long time ago in a land far away we drove NY to Bisbee AZ non stop, plus other grueling driving-thons across the nation. Now it is the 330 rule, 330 miles or 3:30 pm and the driving is done and no driving on heavy wind or rain days. Driving in snow, not even an issue, no way no how.

RE: Overhang construction

I checked my RV over pretty good before I bought it and saw no water damage/rot. Doing some work and oh my found some rot. The bottom 2x2 around the edge of the floor was rotten. The 2X2 at the bottom of the wall it is attached to is fine. Color me confused. There are no signs of rot in the overcab when I purchased mine, clean as a whistle. After a year or so rust marks started to show in the overcab aluminum and got worse and are now holes. Other than that the inside is clean, no water stains no plywood coming apart, nothing, nada, zilch. Pull trim screws on the side and they are rusted away!
