Ok,
So i have added the Tent to the Camper.
removing the items i no longer need - wooden tops, gazebo, step, old tent, tarp, old poles, old kitchen etc saved me about 85 - 95kg.
The new tent + poles + extra room, everything is around 150kg, so im up around 60-70kg.
New tent happened to fit well in regard to the steel frame lined up with edges of camper cupboards / front edge perfect allowing easy weather seal strip to be used.
As these older campers sides are basically connected to the floor only (wood / can get rotten) they have tendency to sag / twist.
I fixed the back prior to first use a few years ago with bracing and extra brackets around door, using some 300mm angle bracket 4mm thick, welded to trailer and propping up side / rear of camper.
I did the same to the front this week, i jacked up the front corners of side of camper just to remove any sag it may have had (minimal 5mm maybe) and welded in the plates. i can now sit and bounce on the corner and zero flex (i weigh 92kg) so safe there.
Orig aim was going to be to use the piano hing on one side, but the way the tents are made (to really go on a 4 foot or 5 foot wide trailer) would mean to do so and mount to the steel frame the tent would have then overhang one side by 8cm and leave 30cm on other and really lop side the trailer.
the tent is made for a max 120cm drop, my camper is 105 + then mounted has a 8cm horizontal distance before it can drop, still less than 120cm so works. Also the bottom half of the tents cover folds down over the side of the trailer so further protects from any rubbing on side of trailer.
The top of the trailer cupboards i lined with aluminium / aluminium edgin + silicone etc as during transit without this the wood cupboard tops could get wet. When parked up at home i have another tarp to go over the lot and when camping the bottom section of tent cover folds back over protecting camper
The tent then sat on camper great, sealed with weather proof tape / foam stuff that runs along top of aluminum leaving 8cm exposed out to edge, runs across front of trailer then i had to add some wood to enable a seal at the rear and a extra piece of wood to add depth and enable a seal for the back door.
As the front of the camper was solid as now with brackets and the front steel bracket of the tent frame sat flush on top of the trailer front frame front bracing was a little tricky. I felt the best solution was some metal plating, 45mm tech screws into the tent frame and then proper nut / bolt and lock washer with a rear support piece of steel on inside of camper to spread the load and support the camper metal. Did a few with pop rivets but wasnt as confident as using tech screws and actual nuts and bolts / lock washers.
Is as solid as can be and with 16 screws / nuts and bolts holding it on there is a lot of backup as i dont think they can all loosen all fall off at once. Pic is upside down for some reason when embedded.
Then came the rear, as i had to fix the camper and not use gas struts i wanted to enable use of rear door, luckily the tent base is designed that it has two massive 50cm x 120cm trap doors under mattress, another nice coincidence is the width of camper internal is 122cm
so with these and rear door i was happy access wise. I deliberated for a day or two as i didnt want to just secure to rear thin trailer steel, then i clicked that i could make a brace that would server multiple purposes
1. affix to tent steel frame to hold it onto camper.
2. sit flush along body so i could then tech screw trailer rear sheeting to the brace from the inside as another way to stop any sag.
3. affix the brace to the actual trailer steel frame with an angle that then also holds up the back trailer steel so even if floor rots it cannot sag.
so i knocked up these 2 brackets.
They fit perfect (another fluke) between already present tarp hooks and my combination lock for rear door / hinge for rear door so i can still open door to 90 degrees.
i have tech screwed them to the trailer and to the frame. i would rather leave it like this and not weld, just in case i want to remove. pretty sure tech screws dont just come loose ? i would check regularlyNext step was after research i realised that though i only have the single drawer bar, its design is the best variety of single bar as in the actual draw bar runs from hitch to rear of trailer and everything is built around that. Still i wanted to brace it. i researched the best ways to brace it and decided on a ladder style brace like below.
I decided to use the 30mm sqaure tubing as i had some from other brackets, its nice and strong etc.
From the instructions above i could see the most important is dont weld underneath on current draw bar as you dont want to create a fatigue area, hence i added the plates which are 85mm, giving me 5mm each side of draw bar to weld it to draw bar and not compromise the bar. I made it last night and have painted it. i plan to add it tonight, though still a tiny bit hesitant as last thing i want to do is ruin a weld and damage draw bar. I think i have decided i will not do it yet, im heading to dromana for weekend to test tent, after the weekend i will add it, then if i stuff it up i have time to repair priro to easter. if i just do small tack welds and take my time i dont think i will stuff it up. My welds are not too bad for zero training just bit of trial error practice, maybe a 5 out of 10
Any info / advice would be much appreciated especially from someone who has done draw bar bracing etc.
Also i rang RACV for no premium increase they have added tent at full RRP
so im happy about that.
