  1. I see your point, but taking a lead from the thread title, the difference between a powerbank and just a battery is one of packaging. A powerbank is simply a battery in a case, and packed in with it can be all sorts of extras, charging regulator, 5v regulator for USB, lamp, inverter, tyre pump etc. Reading into the first post, there is also the lead/acid v lithium issue, which to me seems to be the crux of the whole question.
  2. The underlying question here is which battery technology, lead/acid or lithium? Lead acid is traditional, heavy, bulky and cheap. Lithium is new, light, compact and expensive. Further complicated by the fact that even though both may be nominally 12V, to get the best out of them they need different charging regimes. At present, all caravans are fitted with chargers designed for lead/acid, so to change over is not cheap. I know that lithium leisure batteries are sold with integrated charge regulators to enable a straight swap, but the price! The price of lithium may well come down unless it becomes scarce, in which case it may go up! Although, for a caravan, the weight saving of lithium is very attractive I cannot see the industry changing over in the near future. Also, at the moment, I cannot see many caravanners being willing to both break with tradition and dig deep enough into their pockets for a few extra lbs for an unfamiliar technology.
  3. Have been there two or three times for rallies. We have always had well cut level grass with ehu. The home made cakes in their cafe are delightful but fattening!
  4. This idea is not totally new, and previous versions have all failed to catch on. A few things to consider:- Different versions will be needed for different vans, even year by year updates to the same model van. Caravan manufacturers already consider aerodynamics but do not come up with an answer looking like this. This could have an adverse effect on caravan stability. Slightly different designs may be needed for different towcars, even with the same caravan. I applaud your effort and thinking, but fear you are barking up the wrong tree.
  5. All three points can apply, plus you could have a blockage such as fat, tea leaves or hair from the shower. A little gurgling is more or less normal but backflow should not happen. Most vans have two or three waste outlets and any joining of them together should be as smooth as possible and as far down the pipe as you can. A "Y" connector is much better than a "T". Long coiled waste pipes are not good, I always carry several lengths.
  6. You say that the battery is fully charged, but how do you know? A dead battery may sometimes appear to be fully charged until you try to use it! Incidentally, and no offence intended, but posting in all capitals is often considered to be shouting.
  7. Is the mark in the vicinity of the repair? What type of repair? If the mark was caused by the repair it is their responsibility.
  8. Look at Doosan's reply, but remember that for his option 1. there are variations to suit different connectors to the van. For his option 2. you may need different fittings for different makes of barrel.
  9. You need to consider what types of sites you are going to use. On level hard standing you don't need anything. On level grass or loose gravel the ones that fasten to the steadies are fine or you can just carry around some wooden (not chipboard or mdf) offcuts. On sloping sites such as many rally fields you need some kind of levelling blocks, either an assortment of different thicknesses of wooden blocks or you can get stackable plastic pads. Most caravan accessory shops sell quite a few different types, you pays your money and takes your pick!
  10. I know that a lot of people do use single axle movers on TA vans. The only issues they seem to have are difficulty rotating on the spot on soft surfaces where they seem to dig in and mounting kerbs where the undriven wheel is on top of the kerb taking all the weight and the driven wheel can't get any traction. They seem to get by though. I don't think that the extra battery drain needs to be worried about because moving the van needs the same amount of energy regardless of how many motors it is divided between.
  11. A 10W panel will normally be enough to keep your battery alive over the winter as long as you do not have any parasitic drains. Probably nothing to spare though!
  12. If you have to ask, you may well have the skills to fix it, but probably not the skills to do it invisibly. GRP repairs are easy enough, doing them well is much more difficult.
  13. Have you replaced either the pump or shower head, allowing more flow and simply using the water up quicker?
  14. So true! It seems to me that the extremes are getting further apart. Many people seem proud that they know nothing about how things work, but on the other hand there are many people who still get frustrated that so many things are made these days in ways that render them virtually impossible to repair when they go wrong.
  15. Yes you can. This used to be a common practice when there were far more sites without ehu and far fewer vans had solar panels. In fact, in my bits bag I might even still have the lead that came with my folding panel to do just that. Quite a weird plug on the other end and the panel came with about 3 different connectors to plug in in different places.
  16. I have, in the past, used sprays which claimed to penetrate and then evaporate, leaving only graphite or PTFE dust (I cannot remember which). I have not needed it for years so cannot name brands or retailers.
  17. There is a bracket kit available which enables it to be fitted into the doorframe in many cases where there are obstructions to direct fitting. Still adds little to security though!
  18. If that happens, whatever you do, DO NOT pick up the cut end until you are 100% sure it is no longer live! Very easy to forget in the heat of the moment!
  19. Joining ehu leads end to end is not good practice but sometimes necessary. Also not good practice, but also sometimes necessary, is running ehu leads where they may be driven over, form a trip hazard or are at risk of falling victim to a lawn mower. All you can do is assess and minimize the risks for yourself! If you must do any of these, there are things you can do to reduce the risks. Keep the connectors dry. Make the leads and connectors easily visible. Use thicker cable if they are going to be very long runs. Physically protect cables and connectors from being driven over or trodden on. Limit current consumption if long runs are involved. etc.
  20. Yes, but.... +E on your licence qualifies you to tow a lot of different types of outfit. A horse box tows very differently to a caravan, as does a glider, a boat, a car on a trailer, etc. all different to a caravan and different to each other. The test covers many of the aspects they have in common hitching, unhitching, breakaway cables, safety precautions etc. It also covers aspects such as reversing, the principles of which are constant across all trailers, even though they feel very different. To be fair to all candidates the test has to be based on some form of standardised trailer, why should this specifically be a caravan when many drivers have no intention of towing one?
  21. Yes, tyre pressures can make a huge difference! "Back in the day" towing was not as different as you imagine. Stability was still a problem if you got things wrong but outfits towed as well as they do now if you got it right. Modern aids like ATC and stability programs in cars only help out if things go wrong. Many cars were very low on power so lots of gear changing on hills was normal even solo. Good roads were few and far between so speeds were lower anyway.

    The daft question is the one people are too daft to ask!

    Yes it is. Just like every mainstream UK caravan. The max weight for an unbraked caravan is so low that it is virtually impossible to build a caravan below it.
  24. No, they are not road legal but need the wheels to pull them up onto a low loader. Sometimes they are positioned by crane, and for this they would not require wheels at all. I believe that legally they require wheels and a drawbar to qualify them as a caravan for planning permission and building regs.
  25. Be careful! Many cleaning products destroy any waterproof properties of awning fabric. I have no idea how this will affect it.
